Black screen launching Cyberpunk from gamescope-session

Goal: Play GoG Cyberpunk with HDR

So I installed Cyberpunk on GoG and added it to steam, then switched over to a gamescope session, but after launch, the only thing I see it black screen, the game launches just fine on regular desktop(hyprland) so it seems like gamescope-session X heroic issue. Any pointers would be highly appreciated. I'm not stuck on gamescope-session, but it's the only way I know to get HDR(well, and plasma 6 beta, but that's not ideal)

Tried: Using gamescope-fg wrapper as linked in ChimeraOS/gamescope-session
