What the expected behavior or effect is. If possible include the error message.
In the scene provided, I have drawn two lines. One is a NURBS curve, the other is a simple plane that I've deleted three of the sides off of, and then extruded the vertices off the ends to create a "curve".
Using geometry nodes, a sphere object with a basic material with a base color of AMD Red is instanced on the points of both curves.
The curve made of an actual mesh produces the expected results, with the sphere being placed at each of the vertices on the curve.
The curve which is an actual non mesh NURBS curve, however, clears the material off of the object, and no amount of applying set material in geometry nodes will fix it.
Steps to Reproduce
Scene provided above, simply open the file and flip between RPR and cycles/eevee. this happens in the viewport as well as when doing a render. Have a look under the instanced objects geometry nodes for the extremely basic example.

Ticking "As Instance" makes the material work again, until "Realize Instance" is used, at which point, the materials are cleared again.
