Game works fine but since Friday whenever i try to join other players in the lobby both the game and steam crash instantly without any errors, can still load into the match by myself, tried running different versions of Proton and GE-Proton, with or without launch options, nothing changes
Also Steam chat was working really slow when it all started but works fine now

Steps for reproducing this issue:

  1. launch Deadlock through Steam
  2. Accept a party invite
  3. Steam crashes with the game
