a friend of mine i gifted the game too has trouble logging in

same problem

Stupid infinite login. Been happening since halloween 

Or rather since ps5 version came.

The servers think u have already logged in so it wont let you just keep closing and opening the application.

It sometimes takes a few trys but it works. 

Sometimes it takes like up to 5 minutes to let you join so just keep spam closing and opening the app. 

Hope this helps.
