[STEAM][0.90.11][COOP] Sync loading stuck if EPIC is the HOST

Join a game where EPIC Version is the Host

  1. When I am the Host in Steam Version, then the EPIC Version can join my game.
  2. When the EPIC Version is the Host, then the Steam Version cannot join the game.

Screenshot when joining the Host of the EPIC Version from a STEAM version.

Thanks Megavolt, investigating.
