Thunderbird freezes
I'm running Thunderbird 128.5.1esr (64-bit) on Windows 10.
After it has been running for some time (usually half an hour), Thunderbird starts freezing up. It seems to be stuck at getting new messages from the server.
I can't close the window when writing a new message, I can't read e-mails and even closing Thunderbird doesn't work. I have to maually end the process in the task manager. CPU load and RAM are not affecter and all other programs on the computer work fine.
If I run Thunderbird in troubleshoot mode, these issues are not present. I have no active extensions (just one disabled), I'm using the default theme.
Any ideas what could be causing these issues or how to troubleshoot this?
