Resolution Note:
The project uses OpenCVForUnity for processing. In particular, in script GrayScale, the call OpenCVForUnity_MatToTexture() is used to copy results to a Unity texture. This call writes out of bounds to the Unity Texture2D dstTexture. In particular, 2081600 bytes instead of 2073600 bytes were written out, causing memory corruption and Unity to crash. Unity is working as intended, there seems to be a bug in OpenCVForUnity_MatToTexture().
