ULM unrecoverable error: 0x5

Starting any VM in VMWare gives me the following error:

 

 

VMware Player unrecoverable error: (vcpu-0)

ULM: fatal error: 0x5.

 

 

I do have Hyper-V enabled because I need to use WSL 2 and VMWare side by side, but that shouldn't be a problem according to VMWare

What could be the problem?

(Attached: vmware.log and the output of "vm-support")

Host OS version?

Player version?

VMWare Workstation 16 Player - version 16.1.0 build-17198959

Host OS is Windows 10, latest Insider build 20277.1

Hi,

Most likely caused by running on the insider build.

Fair enough, I'll check on a friend's machine running stable Windows and report back in a couple days.

It actually stopped working in build 20270 - prior to that there has been no problem running in insider builds.

What I have found -:

VM configured with >1 processor -> it wont power on at all and gives the ULM error 0x5

VM configured with 1 processor -> powers on and starts booting but crashes when the USB controller is accessed with same ULM 0x5 error

VM with no USB and 1 processor  -> appears to boot.
