my thunderbird has been stalling and "not responding" for two weeks now

Hi, For at least two weeks, Thunderbird has been stalling, not responding, and crashing (but not the type that sends a crash report). Every time it begins downloading messages, it stalls. I compacted folders, checked what your forums recommend, and still nothing. I have Thunderbird on a Win10 XPS laptop and a Win11 Dell desktop, new and full of specs. Uninstalled it and reinstalled it. Same. There has to be a bug in the new version, my guess, since it was working perfectly until the latest update. See images from my Win10 laptop right now. Please advice!!! I am at wits' end since I need Thunderbird to do my emailing!!! Or else I will have to find another email handler.
