Heroic, Proton+UMU, and Steam's Shader Caching Setting

I can't open Heroic in desktop mode on my deck after the latest updates went out. Running it from the command line gives the following:
flatpak run com.heroicgameslauncher.hgl
[13:1215/115304.093011:ERROR:ozone_platform_x11.cc(245)] Missing X server or $DISPLAY
[13:1215/115304.093064:ERROR:env.cc(258)] The platform failed to initialize.  Exiting.
/app/bin/heroic-run: line 6:    13 Segmentation fault      (core dumped) zypak-wrapper /app/bin/heroic/heroic "$@"


I tried running rpm-ostree install plasma-workspace-x11 to make sure it had the xorg fallback installed, but it's still booting into Wayland right now
