Comment 1 Sam 2022-05-16 13:38:48 UTC 
Right after taking the backtrace and starting kate again, it started working. Removed the kate config (as shown in the first msg) and restarted it and it's back. So far it seems to be a config issue.
Comment 2 Sam 2022-05-16 13:47:33 UTC 
Sorry for the 3rd message, kate seems to suspend instead of dying when it crashes.
