Invalid [9.12.12] - Mi9 - Cannot play any video from gallery app

[GazdaPL]

I am unable to play any movie recorded with the camera in gallery app. It shows Unknown Error (screen in polish language ). It happens only in miui gallery, other works fine.

Mi Video doesn`t show any files too.

Edit: Cleaned cache few times and it worked after disabling permission to storage and granting it again.
