Windows 11 Media Player gives an 0x80070323 error when playing an MP4 file

I get a 0x80070323 error when I play an MP4 file on my computer and then close the actual folder the file is in. I shouldn't need to keep the folder open just to play the file. Jesus Microsoft is getting more and more frustrating to use. Any solutions?

    Open Control Panel > Programs > Turn Windows features on or off.

    Uncheck Windows Media Player, click OK, then restart your PC.

    Repeat the process and re-enable Windows Media Player to reset its settings.
