[Solved] - reshade install has broken my openXR runtime.

I tried installing latest reshade on Bioshock VR mod, but it broke the HUD and other 2d game elements.

So i uninstalled Reshade - and now Bioshock VR mod is broken with error "no openXR runtime".    Bioshock 2 Vr mod and Infinite also give the same error.

I have deleted Reshade from registry, and removed "crosire's reshade injector" from "Steam VR open XR api layers", but has not fixed problem.

So in situation where installing then uninstalling Reshade 6.8.0 has broken the openXR runtime, how do i recover it?
 

SOLVED - turns out "reshade broke my VR game" is a common issue, deleting C:\ProgramData\ReShade fixed the problem.

Why did uninstalling reshade not delete this folder automatically?
