Frameworks Version: 5.113.0
Operating System: Linux 6.7.4-100.fc38.x86_64 x86_64

-- Information about the crash:
Sometimes I have to restart plasmashell for the night light widget successfully activate the night light. 
I restart plasma from the terminal using "plasmashell --replace", and sometimes it crashes when restarting. This doesn't stop the restart procedure, since 2 seconds after the crash, plasma comes to life again (i.e., the crashing plasma is restarted automatically).
I can't distinguish anything different in what I do between the times when I restart it and it crashes, and the times when I restart it and it doesn't crash.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
