This issue is caused by kde-gtk-config and downgrading it to a previous version fixes the crash.
This stacktrace is not very useful. Since you are on Arch could you please compile kde-gtk-config from 5.20 branch and show the extended stacktrace?
I did a mix of building the package myself, using the official one, using the previous one and rebooting a couple of times. Anyway, now I am on the latest official version and it works correctly. So unless anyone else has the same issue I would say we can close this.
Ok, thanks. :)
