Unrecoverable error: (vcpu-0) VERIFY bora\vmx\main\hostWin32.c:561

My workstation suddenly started to show this error. Used to work without any problem. I upgrade it from 17.5.1 to the latest version. Checked NVIDIA driver and Background Application Max Frame Rate is set as "Off". But the error persists. Don't know what I should do next.

Do you mean that it stopped working after the Upgrade from 17.5.x level? There are literally tens of such claims here with all kinds of things.

There might be something to do with that error, but I haven't upgraded from 17.5.2.

Hi, the problem showed up first. Then I tried to solve it by upgrading Workstation to 17.6.2. Problem remains and then I reversed my guest Windows back to initial conditions with no apps being installed. Didn't work either. I downgraded a bit of the memory size of the guest, undid the "3D Acceleration" option in the graphic settings, double-checked the NVIDIA Control Panel settings (both of the parameters related stay as "OFF") , turned off my antivirus app and rebooted my host OS twice. Nothing helps. The error keeps popping up when I ever run the guest Windows. But somehow everything is fine when I run my guest Linux Mint solely and there shows no error. So I'm quite confused. I can't find any similar cases with error code 561 so far. Don't know what it means.

bibinosa Ticket has been raised internally, relevant team will look into the same.

Much appreciated.

I have been experiencing this problem for months. The error triggers when I have 2 or more Windows Guest VM running.   I did a "restore"  to the "Manage 3D Settings"  in the Nvidia Control Panel and so far so good.

Tried this trick but sadly it didn't work for me. I suspect my situation is related to the guest OS' compatibility issues (an old windows 8).

Hi there, eventually I just set up another windows 10 guest and seems the problem is gone. The glitching one was an windows 8 guest. I did do the guest upgrading process after upgrading my Workstation but there might be something unsolvable through that.
