Really slow to load and 'not responding' after Tuesday Windows update.
Am I the only one having problems since the Tuesday update? I have win10 Pro and Thunderbird 91.2.0 64 bit. Initially, Thunderbird did not load completely, so I reset the computer. Then it did load, but very slowly and switching folders would take so long that not responding would pop up several times. after a while, things begin to work fine. But the next day I had to go through the same thing.

What is the antivirus, and its settings for email? Using a language pack?
I just use MS Defender with default settings. I don't think that is connected because Thunderbird had the problem after I restarted following the Tuesday Update. However, if I'm the only one having this problem, then it probably has nothing to do MS and my setup needs more study. I was hoping to be able to read forum posts from other people, but I guess Thunderbird help doesn't work that way.
What is stopping you from searching the forum?

The type of problem you have is common, but there are myriad reasons, so it's usually recommended to perform basic diagnostics, such as running TB in safe/troubleshoot mode (hold Shift when launching TB).
Language packs are a known source of your kind of problem with TB 91. Using one?
I don't know what a language pack is, so I don't think I have one. I did find the Thunderbird support forum, and I don't see anything related to October's Tuesday update from Microsoft. The problem must be with me and I will have to try to investigate further. Safe mode will be a good place to start.
Thank you for your help.
