Did some further testin.
It /does/ launch to the menu with Proton 6.3-8, albeit with the classic "can't decode media" screen in place of the splashscreens
Hello @thecookie94, there's a couple years of development between Proton 6.3 and the current build of Proton Experimental. Please note the nearest pair of Proton versions that you can easily test between 6.3 and the regression to narrow the time frame that a Proton dev needs to ponder.
breaks when switching from 6.3-8 to 7.0-6. 8.0-5 not working, 9.0-1 not working either, nor does Hotfix or Exp (as noted above).
It seems that starting with 7.0-6 it tries to play the splashscreen video files (instead of just showing the test pattern), and that's when things go wrong. Likely codec/video decode related?
