I upgraded VirtualBox to version 6.1.12. While using my guest Debian virtual machine, I got the blue screen of death(BSOD) on my Windows 10 with PNP_DETECTED_FATAL_ERROR. I can only use my guest Debian virtual machine for a couple of minutes before it throws the PNP_DETECTED_FATAL_ERROR. There is a bug created for this at https://www.virtualbox.org/ticket/19326.
I revert back to version 6.0.24 and the blue screen of death did happen anymore.
