AFAIK lvl 6 secret portal on the right should give achievement for finding secret level or cake or something but it just loads me back to main menu

Always getting "Unable to use Instanced Stereo Rendering: Cannot render an instanced Stereo-enabled project due to a missing functionality on the system. Please check log files for more info." error. Any ideas how to fix this?

This game is utterly and completely unplayable in vr, it shaky asf and just straight up doesnt work, i thought it was just my old pc, until i traded it for a ryzen 9 5000 series with an rtx 3060 and 32 gb of ram, and yk what, same thing, disgustingly shaky so much i want to vomit from motion sickness...

I want harder difficulty 'cuz it's not hard enough I want to suffer physically from this difficulty
