Request cannot be completed. It will be returned to the main screen

This software has always been kind of buggy, but I still like it and use it every day.

I watched a bunch of movies last night, turned off my tv, and then tonight when I sat down, no matter which subfolder I try to go into, I get the same error, "Request cannot be completed. It will be returned to the main screen". I've rebooted the mezzmo server, updated mezzmo, rebooted the computer, rebooted the router, and turned the tv on and off multiple times.

I'm out of ideas. What could possibly change the entire library's ability to be seen since last night? I haven't used the computer or the TV since I last watched movies.

Thanks

Oh btw...I have a 4k Samsung 65 inch TV.
