I don't know why Eevee works well, but Cycles creates weird patches in the material and I don't know what to do.

The problem is that you have faces that's located at the same position. Take a look at example. Here is the default cube in cycles:

Nothing special. Now I duplicate the cube and move it in x direction, while Y and Z remains unchanged.

As you see, there is a black where faces overlaps.

Now I will move cube so that Y ans Z positions will be different:

This also apples on faces in the same objects. So any time then you will have overlapping faces, you will get this problem.
