SUMMARY


STEPS TO REPRODUCE
1. Boot
2. Start session
3. Watch notifications pop

OBSERVED RESULT
Many error notifications

EXPECTED RESULT
No error notifications

SOFTWARE/OS VERSIONS
Windows: n/a 
macOS:  n/a
Linux/KDE Plasma: 6.9.7-200.fc40.x86_64 (64-bit) 
(available in About System)
KDE Plasma Version: 6.1.1
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION
This doesn't happen at every session start, but at most. When it does, the login process feels a little bit slower, but I didn't measure that.
