Here is exact notification I'm getting every time when restarting my Mac and when I click on notification...
"Background items added.
Arturia software centre added items that can run in the background.
You can manage this in login items settings"
Needless to say that no matter of my settings - notifications on or off, background items on or off, this pops up in notification centre every time I restart my Mac

It also will pop up if I click on notification as well... WTF

BTW; I'm on macOS 13.1 (latest)
