ADDITIONAL INFORMATION
Comment 1 Luca Beltrame 2022-11-20 00:51:42 UTC 
Actually the fault is in ksystemstats.  https://invent.kde.org/plasma/ksystemstats/-/merge_requests/43 implemented part of its changes in the GPU-agnostic part of the backend, but the AMD GPU backend was not updated, so it tries to access a null pointer and crashes during initialization.
