Rocket League not launching - Gentoo Linux

I reinstalled Gentoo not too long ago, and since then I've been unable to get Rocket League to launch. On the old install it "just worked". I've tried with numerous versions of Wine(GE/Proton/LoL) with same (or similar results).

I'm all out of ideas and having trouble deciphering anything useful in the logs and looking for some help.

Thanks
