Question marked as
Agreed with dialabrain that it looks like there is another open window that requires attention in the same app, (Finder), before other windows in the app will respond.
If this is the case, you can respond to the prompt, disconnect the connected phone or device, and or relaunch the Finder:
How to force an app to quit on your Mac - Apple Support
If there isn’t a connected device, the window doesn’t respond when selected, or force quitting doesn’t help, I’d try shutting down your Mac. If able to, hit the Apple menu > Restart and uncheck the option to reopen windows when asked.
