I have tried hints above, renameing cache, uninstalling and reinstalling, renaming directories and reinstalling. I get past selecting PC as core and signing in and then it hangs at Room symbol.
Task manager says RAAT server, Roon, and Console Window Host are running with 0 activity
I have rolled back the driver and tried to start unsuccessfully. Then removed it and reloaded the display driver and again same problem. Get past login, and then stuck at roon logo (half circle and audio signal). Just hangs forever
I’ve moved your post and responses to their own thread, that way support will be able to see it better. @support prefers each new incident be their own thread, it prevents getting things mixed up between users.
We’ve seen Windows updates cause issues with graphics drivers which results in this behavior. What is the GPU for your device?
When you uninstalled / reinstalled, did you use Windows to install the driver, or did you install the driver directly from the manufacturer? Windows’ automatic driver updates can sometimes be a bit flakey, and we’ve seen direct downloads from the manufacturer help in cases where Windows installations did not, so it’s worth a try if you haven’t gone that route.
