Black Screen After Windows logo after battery failure

[shouse]

Using VMWare Fusion 12 on Big Sur 11.2.3 on a Macbook Pro. Guest OS is Windows 10. Depleted my battery today and then plugged back in. Upon opening Fusion, VM started with windows logo. Then went to a disk repair screen, and then when complete went to a black screen. This behavior is typical of any time that I power down and restart the VM, except it does not repeat the disk checking. I do see the Disk and Ethernet icons flashing blue now and then, but otherwise just black screen.

I do not have a recent snapshot to revert to. What is my best course of action to get back up and running? Thank you.

Questions and random thoughts.

What Fusion 12 release are you running?

And, what is the MacBook Pro model that you're running?

Are Shared Folders enabled? If so, disable them and see if they symptoms change.

Having the VM go to disk repair after a power down is not normal behavior for the VM. You have something else very wrong with your VM if that's happening. How are you powering off the VM? You do have VMware Tools installed in that VM so that it will shut down gracefully when you power off the VM from the GUI, don't you? (otherwise you are crashing the VM every time you power off using the Fusion GUI).

Are you storing the VM in a location that's being managed by iCloud Files or OneDrive or Dropbox?

Do you have an AV utility installed on your Mac, and is it configured to scan the location where your VM is stored (if so that is very bad, stop it).

Have you tried booting the VM using Windows recovery or installation USB media and perform repairs from there? Or booting the VM in safe mode?

macOS 11.2.3 is several releases behind and contains some pretty serious security vulnerabilities. , You should consider upgrading It to the latest macOS 11.7 update because there are a lot of critical security fixes since 11.2.3.

Fusion 12.0.0, Macbook Pro 11,5 (15" Mid 2015).

No shared folders. 

Yes on VMWare Tools.

No on VM location. Default location in documents folder.

No AV.

Yes I agree on the updates....I have had to run some mac software at our place of business that went EOL and has been unsupported for most of this year, so I have been leery of updates until I can fully part ways with that software. I'd love to be on an Apple Silicon computer...but Windows is still a necessity for me and I'm holding out for future ARM/Windows/other software developments.

I fully expect that my battery depleting abrupt shutdown corrupted some files in the Windows OS. I have spent some time trying to go through the recovery process, but for some reason it doesn't want to cooperate. I have tried repairing via any method I could find, reinstalling Windows in place via original USB drive and internet, but no dice so far. I get errors on repair attempts, errors on internet recovery, and a loop of booting to USB, starting the install, restarting when asked, and reinitiating the USB install...rinse...repeat.

I do have an old copy of my VM backed up somewhere, but stand to lose some time putting things back the way they should be. That may be the way forward though.
