Prefab background color does not work

As the title suggests.
Working on a project for a couple of months and randomly the background color while editing prefabs just broke. Instead of the background color that is normally there, it is replaced by a green-screen-esque green color. This is a problem on every single prefab in the project.

The background color that is supposed to be seen is the regular dark blue that is by default, and we have found no way of getting rid of this color. Changing the blue background color in preferences > Colors didn’t do anything. The only temporary fix we have is using the skybox when editing our prefabs, but that is not preferable as we would like to have a solid background color that we can change (also we don’t like the idea of a setting not working).

I’ve not been able to find anything related to this problem anywhere online. The problem seems to only apply in the “Shaded” shading mode, as the background color is normal in “wireframe” but not in “Shaded Wireframe”

We are using URP, could the problem be there somehow?
Hope someone has experienced this and knows what we can do to fix it! Thank you!

It must be frustrating to have a bug like that. Did the bug reproducible if you make new project? Have you tried delete Library folder? What’s your Unity version? What URP setting did you use? Would like to see your custom pass if you have one.

It was the Library folder! Still no real idea of what caused it in the beginning. This happened in a collaborative project and randomly appeared on different people’s computers at different times and finally on mine.

I feel like the green is some sort of shading error that URP spits out as green, but I don’t know enough about URP to say anything for sure.

But deleting the Library folder worked! Massive thank you!
