Tried select unknown importer for id. Why are the models purple and give a lot of errors?

Question

3D

After launching any layout from Unity, it gives errors from the second photo, and after starting the game mode, it gives errors from the third photo. If the project is new, then the errors are only from the third photo. Also, after saving and exiting the project, it no longer starts. The screenshots show the very first version of 2020, but this thing also happens with the latest versions of 2020.

Answer 1

No shadows, all objects without textures. Sounds like a problem with shaders, in this case pre-installed. What happens if you add a new object and set a material for it?
I don’t know if the video card does not support the technology used, it would give a unit error.
I would try to demolish the engine and reinstall it, although if this problem is traced on different versions, it is worth doing the same for libraries (directx, net framework ...)
On versions 19, does everything work? Then you need to look at what was added and what are the requirements for this.
