TB 102.12.0(64 bit) on Win 11 freezes randomly when composing a message. When it freezes the only way to free my system is to go to Task Manager and end the task. I tried reinstalling TB but the problem still persists. The problem appears to be related to the latest update.

I have updated to Windows 11 today. I have not yet tried to compose an email, but I really do not expect a problem.

Mostly folk with issue with compose hanging up are having troubles with their antivirus program locking the temp folder or file used by the compose process, so Thunderbird just sits there waiting to get access to the file. Do you have anything but defender for antivirus?
