SteamVR Error -203

Date: 25.06.2021
Issue Title: Encountering -203 within minutes of starting SteamVR
Description: My main reason to get a Pimax was to experience VRChat in a more immersive way, but every time I try and play it, it the SteamVR compositor will hard crash forcing a VR shutdown.

I know VRChat is error prone, but I can with 100% confidence say this is not a VRChat problem, because it keeps running perfectly fine throughout all of this, and even when the VR has shutdown I can see the mirror on my desktop show people moving and I can hear and even talk to them.
