Resolution Note (2021.2.X):
The cause of the GL_INVALID_OPERATION is a shader that is not multiview-aware being used with a multiview framebuffer. In multiview, the vertex shader needs to be aware of which eye is rendering to as well as the number of views. Refer to unity's docummentation to find how to adapt your shaders to multiviewa and single-pass stereo: https://docs.unity3d.com/Manual/SinglePassStereoRendering.html
