Welcome to the forum. I’m just another user like you. Roon support does not usually answer on weekends, so please be patient.
I am sure you will be asked to describe your setup and event. For example, when you clicked the Roon icon, what happened? Was Roon running before the Ventura upgrade?
FWIW, I have 13.0.1 too and Roon is running fine, so I’m sure there’s a solution for you. Hang in there.
Just to confirm, are you referring to the issue in this thread (Roon failing to open on Ventura) or your problem with backup locations in this thread: Roon backup file question - #3 by bearFNF
The moderators had split your post into a dedicated thread to provide more direct support. If your post intends to say that the marked solution linked above did not work, then we’d be happy to continue in that thread.
