Fresh install issues loading Sonarr in browser

4.0.15.2941
Windows 11
Debug logs: Sonarr log · GitHub

Hi,

I was forced to do a clean install of W11 and have installed Radarr, Plex, SABnzdb Server, and Sonarr.

Radarr and SAB are communicating with each other fine. But when I try and launch Radarr I get the following message, regardless of browser used.

Having saved the logs for you on gist, I had a read through and seem to be able to see the issue. It appears when it is launching that it identifies that it is already running an instance. After this error, there is indeed an instance running in the sys tray.

Task manager > shut it down > check services just in case (I have it as a start up app not installed as a service, but belt and braces!).

Try and reload Sonarr, same error, same outcome.

I’ve disabled the automatic start up which even after shutting the instance down and rebooting, checking that it isn’t already running in task manager, same error.

Any help would be appreciated.
