Symptoms

I'm having issues with beta testing this game, because when i do start the game launcher pressing start on steam, it actually opens the launcher, but it instantly closes because it says that the game wasn't launched by the steam launch, so i think this issue is related to the steam launch wrapper somehow, can we solve this? I've been suspecting this was related to EAC, but is this EAC or is a steam launch wrapper issue?

Reproduction
