For the last few months I’ve been using Thunderbird with relatively zero issues. Recently it started bugging out and some events from calendar weren’t showing up. Now when I open it most of the UI doesn’t work. I can switch tabs, but in those tabs most of the controls are not responsive.
Not sure how to get logs. Nothing interesting shows up in journalctl or when running thunderbird from the terminal.
I’m using Thunderbird 148 installed from dnf. Any help greatly appreciated!
I’m facing the same issue in Thunderbird from Flatpak

I removed the calendar-data folder from my profile directory and the freeze went away
