Weird problem. Long term Roon user and never had issues. I‘m running ROCK on a Intel NUC 8i7BEH.
Roon 2.0 seems to run without problems.
Problems with ARC though: it connects to my core, plays music for about one minute but then the NUC just shuts off. When I switch it back on, it boots up, cannot connect to the network anymore and shuts down again. The only way to re-establish connection is to re-install Roon on the NUC via USB stick.
Tried several times and the issue keeps repeating.
