Thunderbird 115 won't log on to servers

I've just upgraded Thunderbird to 115.0.1 from (I think) 102. Now it fails to connect to any mail servers, either IMAP or SMTP: when trying to access mail or send it, Thunderbird just hangs and does nothing. I use Office 365. I tried deleting one of the accounts and recreating it, but it hangs at the point at which it says it's checking password. Does anyone know how I can get Thunderbird working?

Sorry -- found the problem. When upgrading Thunderbird had removed itself from the Windows Defender Firewall and didn't replace itself. I added it back to the list of apps allowed through the firewall and it's fine now.
