Unfortunately DBeaver is not as stable as I’d like on Fedora (35) and just today it wanted to restart due to an exception, and that didn’t work any more as it crashed during startup.

If the crash log shows something like this:

Jan 27 10:58:09 dbeaver-ce_dbeaver-ce.desktop[417763]: Fontconfig warning: FcPattern object weight does not accept value [0 205)

Then something probably corrupted the fontconfig cache. You can remove that using:

sudo rm /var/cache/fontconfig/*
rm ~/.cache/fontconfig/*

And voila! DBeaver did startup again.
