Note:  I very seriously wanted to resolve this issue so since I have multiple MacBooks of the same machine (Mid-2012) I decided to Factory Install a fresh copy of Catalina via CTRL + Option + R on startup.  I installed Vmware Fusion Version 12.0.0 (16880131) as a trial.  Amazingly, I was greeted with the Broken Pipes message upon trying to start a new virtual machine, using the default settings. (I made sure the Allow app in Security was given for VMWare, and it was.) but after quitting the application and rebooting the machine (Prior to wiping out a certain folder in recovery console, or with System integrity disabled). After the reboot, everything fixed itself this time! Wonderful.  But afterwards, installing Windows 10 X64 happened in 1/3 the time as it did on Mojave with Fusion 11.x.x (Latest version as of this post.)! And, after installing Vmware tools my processor is not pegged into the red! Cpu Load with Windows 10 loaded and idle is about 5-10% and there is no stuttering or huge delays when using Fusion mode or full screen, or even windowed. Whereas on Mojave, on an install that had been upgraded since 10.8 Mountain Lion (Consecutive upgrades) after installing VMWARE Tools it was practically unusable. So it appears this MacBook is prime still, for basic virtualization as I am now able to fluently work within the Windows 10 Guest OS without lag or causing runaway kernel_task. It seems either the Logic board, sensors or the overall Mojave installation is corrupt on the other MacBook, Or the Catalina and 12 release is just that much better/faster. I'm not sure what the difference between the latest 11 release and this 12.0 build are, but I intend to license the software even though I was initially hesitant that it would run well-enough on this MacBook Retina Mid-2012, and it is. So I am very happy.   To avoid this Mojave and Fusion 11 headache I presume I will just Clone my Mojave to a Backup SSD and use it sparingly when old applications are needed to run from now on, and try to migrate what I can, license and overall machine to Catalina. It seems this Catalina doesn't run hot either, and the fans are at a quiet 1500-2000RPM when running Windows 10, Web browsing with 25 tabs, and downloads active. The same exact tasking on previous install and MacOS would have made the machine run at MAX RPM, with most kernel_task in red in activity monitor, were talking 4000-5000 RPM doing what is just basic load, which is now working perfectly as I've said. I am satisfied with this for now, And my problem is resolved for now. Good luck to anyone reading this. You should not be disappointed with a fresh install of Catalina and Vmware Fusion 12! TLDR: Catalina and VMware Fusion is much better on the second Retina MacBook from 2012, performance is as expected, and it idles quietly, and uses very little power comparatively. 

Regardless, I don't expect to resolve this problem nor do I expect community support for it, Though I have made a thread just incase anyone shares the same issue and somehow has resolved it,   https://communities.vmware.com/t5/VMware-Fusion-Discussions/Performance-Problems-with-Fusion-11-on-10-14-6-Worse-after/m-p/2917997#M179005   And I do appreciate your "Things to try" regarding I believe debug is off completely by default, yes? I have a PC that's 2 years newer which runs windows 10 flawlessly, It makes no sense that my Macbook with the same i7 Series and most recent updates (though Mobile) should perform at a similar level as a VM, No? I guess thats too much to ask. I'll see how a barebones/Unix terminal based virtual machine performs instead of basing my tests on the latest Windows 10, But I see that Kernel_task is basically using the same or more CPU resource than is available to VMWARE Fusion, which means the system is throttling at an equal pace to what its trying to do, and as you've said I doubt I will be able to resolve this without throwing money at the problem. Though software should be more optimized.... In general..

Regarding Mojave, Initially I upgraded from a 10.10 or 10.11 I can't recall, to Mojave. The reason was Blizzard's World of Warcraft game used the newest Metal API and I wanted to see the performance of it versus OpenGL Firsthand. And I did. My system ran at 1880P (The native Retina resolution) and performed 25-30 FPS. This was remarkable for a old 650M 1gb GeForce Video card, As before I upgraded to Mojave my Framerate was only about 10-15 FPS with the same settings at this resolution so I disagree with you that Mojave should run slower on this machine, perhaps CPU related processes do run slower but Graphics calculations seemed to be much more efficient with the newer release.   

Thank you for your response, Sir. I hate to say it, But performance was acceptable last time I used this machine for virtualization purposes, which was back in 2014-2015, I wish I left the version of VMWARE Fusion and OSX Alone as they were fine for running multiple guest OS's, (which were mainly a couple Linux builds and one GUI Windows install for Visio, etc.). I don't disagree with you, I will be upgrading or buying a new machine when I am able to, As of now that is not the case. For a variety of reasons. Mostly because I have multiple Macbook Retina 2012 models to feed parts from, so this thing just keeps going and going. I have a Desktop Gaming computer which I prefer not to use for Virtualization but will use it if its necessary because of performance problems on the Apple side of things. I just wish this was supported better.

This bit of troubleshooting resolved my issue, Although I had to do it a bit differently than discussed here. I disabled CSRUTIL and then removed the folder and allowed it to be recreated by the OS upon reboot, it was correct and VMWARE Fusion 11 (With latest Updates.) ran and launched correctly, however performance is terrible and the guest os's basically are unusable. So this solution is only part of the problem for me.

I just wanted to let you know, I was able to resolve this problem myself with some of the guidance that was posted about removing the /private/var/db/KernelExtensionsManagement folder.  I simply disabled CSRUTIL in Recovery Console, then rebooted my macbook into normal mode (With SIP Disabled) and was allowed to remove the offending files/folder via terminal, I tested VMWARE Fusion 11 by starting it up and it started with SIP Disabled, I assume that it recreated the folder and permissions correctly because I was able to enable SIP again and reboot, and have everything working. Now performance is another story and one I will be trying to address in a seperate post, The guest OS crawls in my Fusion Library and is basically unusable, pegging down my CPU and MacBook Retina (Mid-2012) with Mojave and maxing out the Fans while doing just basic GUI Windows 10 x64 activities. I imagine this could be do to SIP so I tried disabling it again but it is unacceptable even with SIP turned off. There must be a reason beyond my obsolete hardware that this is so slow, I was using VMWARE Fusion 7 or 8 before this and it was perfectly fine running in 10.10.x prior to updating to Mojave and the latest security updates, But save that for another post. I have read that there are considerable amounts of other people having this issue with VMWARE Fusion 11.x on Mojave or other versions of OSX. So I'm stuck with a potentially unresolvable situation Fortunately I am still in my 30 Days trial and will not be purchasing this software if it continues to be such a bug-fest. What happened to the old quality control of VMWARE Fusion such as was found in the older releases? /Rantoff.

I don't have these files when rebooted, Otherwise I would imagine the solution would work, as would removing the Folder. It appears to only be populated on a running machine, which then the folders cannot be modified or deleted. is there any other alternative fix for this? Or for getting access to these files, when the system is booted to recovery?   Thank you. 

None of these folders or files show up when booted to Recovery, And using terminal there. How can I remove this folder is the question. It seems to be a protected OSX File, which is not present when the system is not loaded. What a headache, even for me.  

This suggested fix is not possible for me,  I am running Mojave 10.14.6, with the latest security updates (005) installed.  When I reboot to Recovery Console (CMD + R) and use Terminal to remove the offending files suggested in the Kernel ExtentionsManagement folder located in /Private/var/db/ it is NOT present, nor are most of the populated files. So I tried removing it from my booted machine, and I get operation not permitted when trying to remove the file. Do you have any other suggested fix or method of removing this folder? I have tried everything on the internet to resolve this Broken Pipe error, including completely reinstalling VMWARE Fusion and deleting all associated preferences and related files using an App Cleaner. I do not want to resort to reverting my OS security update just to launch the latest version of VMWARE Fusion 11, and I can't be asked to upgrade to Catalina because I have 80 32-Bit applications that I use. So I am stuck trying to resolve this...  Anything at this point would be helpful.
