Freezes Windows 7 Catastrophically Since Version 91.5.0
I have a strange issue where Thunderbird appears to cause my computer to lock up completely since version 91.5.0. It just happens randomly. I'm interacting with other apps while Thunderbird is open, and then suddenly, everything stops responding. Apps that were open continue to work, but it appears Explorer locks up (the main theme), and then the GUI completely quits working. Thunderbird is stuck in a "not responding" status, and when the prompt pops up asking if I want to terminate the task, I try to terminate it, but nothing happens. Control alt delete doesn't even work or bring up the options such as task manager. It's such a bad lockup that I have to reboot my computer using the reset switch.
Any idea what could be causing it? Also, how come Thunderbird re-opens tabs that I've closed in the previous session?
Running Windows 7 x64 SP1 with the latest updates on a Ryzen machine.

Does it lock up in safe/troubleshoot mode (hold Shift when launching TB)?
Does it happen in Windows safe mode?
For the tab issue, open the profile from Help/More Troubleshooting, Profile Folder, Open Folder, close TB, delete session.json.
It happens so sporadically, that I really am unable to better troubleshoot this issue. Unfortunately, I am getting really tired of my entire system locking up. My file system is going to be nothing but a corrupted mess at this rate.
The issue still happens in 91.6.0. It's like I'm opening a different email account inbox, and it will just freeze and crash all of the apps running on my system. All I can do is hit the reset button which is not a good idea...
I'll run it in safe/troubleshoot mode for a bit, but anything else I can do?
Thanks for the session.json info!
Try TB safe mode, but I think running Windows in safe mode is more likely to point to the source of the problem.
I ran TB in safe mode for a day, and I didn't see it crash.
However, running in normal mode, it locked up my machine again today, and I had to use my reset button again.
I would really like to get to the bottom of this. Again, this didn't happen before 91.5.0
Any recent changes that broke something for older Windows OS? I did see that Tortoise Git broke a bunch of windows 7 stuff in one of their updates that they fixed a few days later, but that seems unrelated to my Thunderbird issues.
I have 41 mail accounts configured in TB. Not sure if that may be a contributing factor or not. Don't use any plugins besides ImportExportTools (which is currently disabled), so I don't know. :(

Is hardware acceleration enabled in normal mode (Preferences/General/Indexing)? If it is, disable it and restart TB. It's disabled in safe mode, as mentioned in the kb article cited above.
I disabled hardware acceleration, but that didn't help. It just locked up badly again.
Launch in safe mode, check 'Reset toolbars & controls', 'Make changes & restart'. Still locking up in normal mode?
