Created attachment 138591 [details] gdb bt from plasmashell I haven't tried to reproduce this yet. I had a lot of apps open when I changed theme. After rebooting, plasma is now in a weird hybrid state, where the apps are all in light theme, but the panel itself is dark. I'm not sure if I'll be able to reproduce this, but maybe the backtrace is useful.
When in this state, changing my theme from "light" to dark works fine, everything goes dark. But, again, plasmashell hangs (and eventually crashes) when attempting to change from dark to light. Then, in the same session, attempting to restart it via plasmashell --replace results in it crashing again. I'll attach a backtrace

Doesn't seem to occur anymore on Plasma 5.24.5. Moving to needsinfo
