MacBook: Finder 'file can't be found' on theme switch

Question

I have been experiencing a weird kind of issue with my MacBook.

Whenever the theme switches from light to dark - either manually or automatically,

I get this Finder pop-up saying the file can't be found. Despite the alert, the theme switches like normal and I'm not experiencing any issues.

This didn't use to be the case when I got the Mac, it just randomly started happening.

What might be the cause and easiest fix?

MacBook Pro 14″, macOS 26.2

I didn’t have any extensions - I did however have the Logi Options+ app as a Login Item. I tried turning it off and the issue disappeared.

The Login Item is necessary for the app to work so I did a reinstall and it’s now fixed.

Do you have any 3rd party extensions that may affect system appearance (file icons, menu bar, etc.)?

See if the problem is present when you boot in safe mode, which disables 3rd party extensions and performs some system cleanup.
