blue screen
Thunderbird causes blue screen in Windows 11. It's very obvious, since it doesn't happen if I don't open Thunderbird and problem normally occurs when I click on almost anything. It normally takes 2-4 reboots before running properly. It makes me nervous!

Does that also happen in Troubleshoot mode (https://support.mozilla.org/en-US/kb/safe-mode-thunderbird)?
Blue screen almost immediately after entering Troubleshoot mode, but after a reboot, nothing so far! Hopeful!

Yes, also in trouble-shoot mode!
Odd! Guess I'd try fully uninstalling TB including user data, then reinstall.
I have already tried reinstallation. Now I have disabled hardware acceleration to see if that helps.
Thunderbird does not make real mode calls to hardware. This is necessary to actually invoke a blue screen, so while Thunderbird may be implicated, it is unlikely to be the actual program at fault.
Several options are; The physical disk may be failing or not "sane". Forcing a defragmentation on the drive will check it for errors and perhaps fix some. It will take time to run, but it can not hurt and perhaps may identify issues that will get worse over time. Because Thunderbird maintains large message stores and updates them frequently it is often the first to strike corrupt disk storage. The antivirus may be accessing the files in real mode as Thunderbird has requested access. So that could prompt a blue screen Memory issues could be an issue, but that would be rare for only one program to be involved. The hard disk is more likely.
Matt is correct, blue screen indicates some flawed software or hardware that isn't Thunderbird. Graphics error is also possible.
