These events happen when I simply power off a vm by closing the vm window top right & then selecting "power off the vm" in the vb menu that pops up

LMK if you need other logs or a dump. Please provide a link to appropriate guide for obtaining such additional files.

I looked at previous posts that have similar error message, but each solution seems unique or I didn't recognize the relevance for my problem, therefore, I am starting this new topic.

Many thanks for your help.

Logs starting the VM from full shutdown provide better diagnostics than a log from a saved-state VM.

Your host is showing a hardening problem, ExitCode=0xc0000005. See Diagnosing VirtualBox Hardening Issues.

Your host also has extra 3rd-party antivirus & firewall (Mcaffee) installed. Try uninstalling that as a test.

I tried uninstalling my antivirus and the error was fixed.

Thanks a lot, scottgus1.

I was wondering if there is a way for me to fix the error without having to uninstall my antivirus?

You might be able to set scanning exceptions in the 3rd-party AV to not touch anything related to Virtualbox or the VM files.

Alternatively, roll with Windows 10's native AV & firewall. It works well and doesn't mess with Virtualbox.

Okay, thanks a lot, scottgus1.
