I am running Windows 10, 64 bit. I have Tidal account and have music on a DROBO NAS drive.
I started Roon, got a message telling me I should upgrade the SW, I accepted and installed the latest build (209) but it then no longer recognised me. I couldn’t log in at all. It didn’t reject me, it just never connected. If I entered the wrong PW it would know immediately.
I uninstalled it completely and downloaded a new version, went through the install but the same issue.
