Sounds like you might be experiencing the same remote issues as many of us have at the moment. When it happens is it locking up or does it still attempt to do things but nothing happens? You loose artwork and then it might get stuck on a page when you goto home and you get the Roon logo ?
There are several threads covering this behaviour but people seem to always blame your kit as it’s easier. Roons investigating this but not got anywhere at all.
