Long Latency in Thunderbird

jl11

TB has started to exhibit terribly long latency lags

I'll be working on TB, and then it hangs for 5-10-15 seconds, if I click on a new feature, the screen goes gray until the latency resolves. Also get the Windows timeout error notice (see image)

After 10-15 seconds, TB resolves on its own and works OK for a little while, but then goes latent again after maybe 1-2 minutes. This is consistent last couple days. I've rebooted, cleaned caches, etc.. and the rest of the Win 11 PC is working fine, fast, no latency in any other program.

I asked my email providers if they were having IMAP issues, but everything OK on their end.

Ideas? TB v. 140.11.1esr (64-bit)

What is your anti-virus software?

Microsoft default anti-virus

Try to create an exclusion in Windows Defender for the Thunderbird profile folder, so that the Defender's real-time scanner will not scan it. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-to-find-your-profile
