Roon Radio: unexpected error


My Roon Radio suddenly stopped working giving ‘Nothing similar to play’ and Limiting Roon radio to library’. I’m still in my trial and already getting a bit worried if the software commonly has bugs and if I should go for the subscription?
I just purchased a NUK8i3BEK2 265ssd 16ram specifically for ROCK which I’ve setup this morning. All worked fine until now.

Can you please help?

This keeps happening very randomly. Is there a fix?
