SteamVR detects a unknown error -203 when it automatically turns of headset screen when you take it of. Also a crash when game lags too hard.

The tittle is pretty much everything. I just started playing with Vivecraft, I use some mods to enhance experience, but I believe they have nothing to do with these crashes (expect lagging Minecraft possibly :D)
What happens after the error is the VR headset screen goes black and I can see the game on my monitor stop updating it's position. Weirdly I can still use mouse to navigate through menus to quit Minecraft!

I'm using Valve index and I have updated drivers on it.
If computer specs are helpful I will give them!

PS. I absolutely love this mod! And if the error happens I can just restart it quick, its just a little inconvenient that I can't pause the game and leave. Currently this might be the most played VR game I have :D

can you post the latest.log, from when this happens?

This is not a Minecraft crash, this is a steam VR error, so I have to look a round for it, expect if a Minecraft log is needed. I will attach it to this comment if I find it.

Edit: I might need help. I have no idea where to look. I found a log folder that contains every Steam log file (including VR), but nothing states error or crash or anything. I did find the folder SteamVR resides in, but no logs found there, or I missed them.
Edit 2: Found dmp files (I just learned about them, they are files dumped by a program experiencing an error). Can't open them tough.
