Unexpected error when starting up Musicbee

[Mario m8s]

On rare occasions when booting up MusicBee, I get this error:
MusicBee v3.5.8698.34385D  (Win10.0), 30 Jan 2025 14:45:

I am running this on windows 11 with the latest musicbee v3.5, not sure if it'll be fixed if I update to the beta v3.6.

Since you're using a version of MB that's more than a year old, you should update to the latest 3.6 as it's possible the issue has been addressed. The only way to know is to update. See the link in my signature for the download link and patch update instructions.

According to the error its when you click on the playlist header panel but i cant tell any more than that. If you can reproduce it (using v3.6) then let me know if you are happy to run a debug version
