Basically, if you don't move the camera, the mesh won't absorb any light or reflection, but if you does, it will, as always while not reflecting, instead...copy the enviroment texture by the direction you moved the camera. something like that.

I honestly don't know why this happened, just while modeling, randomly.
And just so you know, i already tried to update drivers, deleted all of add-ons, loaded factory settings many times, restarted and restored the pc, installed blender in many versions in every way possible, even by Steam.
The strangest thing is also happened to some people i know, while didn't to others.

There have been various reports of rendering issues with AMD GPUs in Blender after driver update 20.11.2 and 20.11.3. Are you able to try downgrading your GPU drivers to see if it helps?

Seems like it's impossible to downgrade AMD Radeon Software drivers, i tried rolling them back from Device management, Display adapters, Properties and Roll back, but it doesn't change anything. Maybe there's something i'm missing.
I also tried to ask some of my friend to upgrade to the newest drivers (since they all haev AMD too) to see if blender would have been break to them too. The answer is no. There could be the possibility that not everyone is hitted by this "bug" or however it can be called. Thanks anyway

Edit: I tried to download drivers again with factory settings and download blender, but nothing still happened

If you can't install an older driver version you could try to enable Render Properties > Performance > High Quality Normals as a temporary workaround. For the general task where we collect issues with these driver versions, see #82856.
