Unfortunately the process android.process.media has stopped unexpectidley

[AC Question]

Hi
I have an android mini M8S box on android 6.1 operating system*that recently keeps generating this message....
I have tried most of the suggestions I could find on a google search including unsyncing and resyncing Google services, reseting app preferances, clearing data and cache in suggested media apps and in desperation a FACTORY DATA RESET, but so far, ALL TO NO AVAIL?
Can anybody HELP and shed any more light on this problem?

Many thanks

Kind Regards

Mick
