Hello @takardo, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/3521#issuecomment-3426719880.
Hello @kisak-valve I feel really silly but I figured out my issue and it launches with ge-proton-10-21 now. I had to right click on the game, click properties and set the proton version in there. Sorry about this and thank you.

Compatibility Report
System Information
I confirm:
- [✅] that I haven't found an existing compatibility report for this game.
- [✅] that I have checked whether there are updates for my system available.
I couldn't get this to work :( Might be because the game never actually starts?Symptoms
Click play on Rocket League and then it says "launching" but stops and the green play button comes back. It never actually starts. It starts in ge-proton10-10 and the issue page said to report here.
