The error in the log reminds me of cases where there is a mixture of code versions on the PC, e.g. where the user has copied VirtualBox.exe to some handy location which is not updated along with VirtualBox.

If so then you need to stop doing that. A shortcut is fine, copying the actual executable is not.

If that isn't it then VirtualBox has not been installed properly. Uninstall it, then install it again but this time run the installer using "Run as administrator".

This one might be the Hyper-V Memory Integrity glitch? 6.1.32 is supposed to have new code to fix this, ttry upgrading Virtualbox.

Or try disabling Hyper-V: HMR3Init: Attempting fall back to NEM (Hyper-V is active). Note the part about IT if you're on a work PC.

Hello. Thank you for your respond, but you probably haven't read logs. Logs shows that VirtualBox is installed in proper location. I installed the newest version 6.1.32 and it fix my problem. So version 6.1.30 have bugs or previous installation process meets any problems or extension pack that I use were problematic.
