After Thunderbird has been open for awhile, new messages will not come in

For the last year or so, and not consistently, Thunderbird will not bring in new imap messages across multiple accounts. Sometimes closing and reopening will make new messages appear. If I close Thunderbird from task manager and reopen it always brings in new messages. When it does start working it will keep working for 1-3 days. Restarting my computer seems to make it work for longer. Running Win 11 Pro, but have the same issue on a Win 10 Pro computer, different antivirus on each computer. Seems to be the same issue as this post https://www.reddit.com/r/Thunderbird/comments/1gxduxt/thunderbird_not_showing_new_messages_unless_i/
