Windows Server 2019 fails to start after today's Windows 10 update

[elderorb]

Hi,

Today I've got Windows 10 feature update and after installed found weird behavior: all my Windows VMs started crashing on attempt to resume live snapshot. I managed to re-create live snapshots for 2k12r2 & 2k16 but still can't fix 2k19. Any ideas how to troubleshoot?

Start the guest from full power off, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

I'm experiencing the same issue and am including the log files for assistance as well. This is also applying to a Windows Server 2016 Datacenter x64 server when I attempt to start them. Thanks for the assist scottgus1 or anyone else who can give me some insight here!
