Beginner issue: after URP update all game objects disapear(in game it's pink)

i finally learned how to apply an instance of the render pipeline. One of them is called URP. However, as soon as i apply the URP asset to the scriptable render pipeline setting all my assets disappear and the scene window turns blackish grey.

The box collider, for example, of a cube i can see but not the material. In the Game window all these objects are pink.

When i tried to create a new project with the HDRP packages already installed it seemed that the errors that were coming up told me that my GPU does not support this.

Im sorry if this question has already been asked somewhere, but i've spent hours on this and cannot find anything about this. Like absolutely freaking nothing...
