Me too and does not let me use the game pad and in the controller display menu all the controller buttons are assigned to secondary attack... so weird

I have 30 mods installed by the way... not sure if thats the cause

Turn off the option to join betas for the game. Verify files just to be sure. Relaunch.

Or try Uninstalling and reinstalling the game. Be sure to find the folders for any mods used (if this applies) and delete them.

Hi... I found though for now that the mod causing the issues with loading a Beta main screen instead of the official was Jotun mod and they have just updated :
