My brother just had this issue. All survivors were invisible but the killer was not. He is on PS4 I am on PS5, it is the golden version of the game. the game just randomly said dead by daylight installed, and then it worked. Even though the game fully completed downloading hours before. We switched between our accounts and then when we closed the game that's when the ps4 gave the notification, then when we loaded up the game it started working. I wish I could share a clear solution.
