Tbird hangs "Downloading Message 1 of ..."
Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)
I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again. No change. Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started. The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances. After selecting whichever has the largest memory allocation I click on "End Process." This all "feels like" a bollixed internal state. Does Tbird store internal-state information in its own file, or is it buried in the Registry? If I attempt restoration from a backup, which files are needed; or is that unwise? I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update? Is there any risk of losing my Inbox, Sent, etc contents?
Thanks!!!

Update: This afternoon, before attempting to start T'bird, I installed the new release *and* restored the "Profile" folder from a backup that had been taken last Friday, three full days before the problem reported above. Then I started T'bird. Problems continue:
(1) Even though there have more than 100 new messages since last Friday, it sees "No new messages", BUT (2) when allowed just to run, the amount of memory being consumed grew steadily from maybe 1 1/2 G to more than 11 G, was still ticking steadily upward when I clicked the Task Manager's "End Process" button.
Since reloading the profile from a backup made before T'bird went off the rails did NOT get it back on track, some aspect(s) of its internal state must be saved or retained elsewhere than in the profile folder. Please, what else needs to be restored to revive normal operation, and where is it hidden???
Thanks...
I suggest you try using your operating systems "safe" mode. It is probably a program that loads when windows starts. If it is not an issue in safe mode, look at the programs that load with the operating system, Include your antivirus in the suspect pool. They are notorious for causing issues.
