Upgraded to 91.2.1 - preferences freezes
Upgraded to version 91.2.1 from an earlier version today and on both my computers launching the preferences from the tools menu causes thunderbird to freeze and then I have to end the process. Is this a known issue as it's happened to me on two separate Windows versions (10 and 11)?
Chosen solution
Does it freeze in safe/troubleshoot mode (hold Shift when launching TB)?
Do you have any language packs? They are known to cause issues like this.

I also had this problem. Although Thunderbird was a bit tricky to get into safe mode, I figured it out. Then, without any add-ons being turned on, the problem went away. Upon further investigation and review of another posting, I removed the US language pack and restored Thunderbird to regular operations and the problem has been resolved. Thanks for the solution!
One of the fixes in the 91.4 version, released Dec. 7:
"Using Thunderbird with multiple language packs caused high RAM and CPU use and sluggish performance"
