Seems to be something in the Garage Mods.
Just went through & disabled everything one-by-one till I got it to successfully allow me into the garage.
Narrowed it down to the Garage Mods. I normally use "Session stats by Awful Tanker" - Enabled it won't get past the login screen. Disabled it gets into garage without an issue.
Unsure if it affects all garage mods or only a specific few, but hopefully that'll at least point in the right direction.
