Vive Pro Eye : failed to read magic number

[Caterina]

Hello,

I’m currently trying to use the HTC Vive Pro Eye in Unity 2020.3.XX LTS. It worked fine one week ago (09/17/2022).

Now, when I run a Scene with the prefab “TobiiXR Initializer”, Unity either freezes or crashes.

In the project log I get the following error.

Cmd: compileSnippet
insize=16577 file=Assets/DefaultResourcesExtra/Skybox/Procedural pass=<Unnamed Pass> cachingPP=1 ppOnly=0 stripLineD=0 buildPlatform=19 rsLen=0 pKW=UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 …

Unhandled exception: Protocol error – failed to read magic number (error -2147483644, transferred 0/4)

Quitting shader compiler process

Does anyone have any idea what is the root of the problem?

Hi Caterina,

I’m seeing the same error message, did you manage to find a solution?

Thanks

Hi, this is a very old version of Unity… can you try on the latest LTS and report back?
