  I have followed this issue and tried the remedies, still did not fix. Unable to use proton (games not loading) #6076
  I also created a post in the Arch Forums, but have not had any luck either. https://bbs.archlinux.org/viewtopic.php?id=279058

I have seen this post which mentions downgrading from the glibc 2.36 > 2.35, but I'm not looking to downgrade my packages, as it has been months since I've updated, and I have other packages on my system such as obs-studio that requires the glibc 2.36 package. (Along with this, Rocket League is not an EAC game) #6051

Symptoms

Steam shows that the game is running, but no window is displayed with the game.

Hello @Ahptt, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to #3521 (comment).
