Are you by any chance using a non-default Plasma theme? If so, can you switch back to Breeze and see if the crash goes away?

Thank you for helping us make KDE software even better for everyone!

It was always default plasma themes, i believe only Fonts were ever changed from the default install (as provided by the arch packages)

But, since 6.1 these went away. I guess it's "fixed"?

Cool, let's call it fixed until it happens again.
