I’m using 25.11 stable, and KDE Plasma.
I recently booted my NixOS drive, and when I logged into my user account, it boots normally, and then I’m met with multiple “crash handler” windows, with similar output:

When I log into other user accounts on the same drive, they log in fine.
I’m only using default KDE Plasma settings, with the exception of one kwin plugin: khronkite
The only way I’ve been able to navigate and still use my desktop is through krunner, otherwise, everything looks blank:
What’s causing the issue in my user account? Do I need to migrate to a “new user” account?
