What Plasma version are you using, and in what distro?

Do you have any custom widgets in the user account that crashes on login?

Hi, Im using plasma 6.1.3 in Nobara 40, I have custom widgets but there aren't any that crash. I somewhat fixed the issue by renaming all kde and plasma config files and now I can log on but I'd love to know what exactly caused it. I also did not mention that I ran dnf update and upgrade and this happened after I shut down the system. Any tips where should I be looking for logs or something?

Can you diff your new and old config files and attach the result — after scrubbing personal information from it?

Those are just a few of the files but i don't think the problem could be from them

martin@martin:~$ diff -w .gtkrc-2.0-kde4 ~/plasmabackup/.gtkrc-2.0-kde4

Thanks. Yeah nothing that looks helpful unfortunately.
