Random crashing of windows guest

[Netstaff]

Both virtualbox virtual machine window and windows 10 guest crashing randomly. Virtualbox sometimes crashes machine windows, sometimes windows guest goes to bsod.
Windows 11 host, AMD 5800x and virtualization enabled in BIOS
Tried:
Memory test
SVGA/VGA graphics adapters
AVG antivirus shut down
Moved machines to a non bitlocker drive
removed windows scaling
virtualbox version 5.2.22
removed .Virtualbox configuration folder and started from scratch

Attaching the logs: pastebin. com/EddCpDj5
Any ideas?

Attaching the logs:

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

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

So the txt was too big for this website, but I'm happy to know now that zips are allowed. This log is from a fresh vm, crashed right during start of windows installation, with an error from virtualbox.

The guru meditated on VERR_SVM_IPE_4, which is a new one to Google's web-search. Your host does not have Hyper-V enabled, but the mention of SVM, which is AMD's 'virtualization technology' (like Intel VT-x) hints to me that something on the host might be getting in the way of Virtualbox's use of SVM. Maybe 3rd-party AV? Shutting down AV often does not truly stop it when it might be interfering. A full uninstall may be necessary for a test. FWIW Microsoft's built-in Defender has gotten substantially better, good as the big boys now, and does not interfere with Virtualbox. AV might also have a scanning function relying on SVM/VT-x which can be disabled.

Windows 10 is designed for two processors, and your host has room to bump up the processor slider to 2. But not more, just 2, please.

I've completely uninstalled AVG antivirus and so far I got rerecord long uptime of all times. It seems to be the solution. Thank you

Great! Glad you're up and running.
