Symptoms

Hi,
I can't start Mordhau. When I launch the game, it crashes in less than a second.
Steps :

• Open Steam
• Select Mordhau
• Press the "play" button.
• The play button turns to a "stop" button for less than a second
• The button turns back to the play button.
• Neither Mordhau screen nor error message are displayed.
  I tried several Proton version, including some Glorious Eggroll one's without any succes, and experiencing the same problem.

Reproduction

On steam, select Mordhau then press play.
