  1. The re-installing on the xbox app actually worked for me, surprise surprise. Thanks for that obvious tip that I and probably others didn’t think of.

  2. For me it worked heading into SteamLibrary\steamapps\common\Crusader Kings III\binaries
    and just execute the game from there. Crashed every single time i did it from steam
