After some testing replacing the materials on the prefab's models fixes this issue. Even if the material is exactly the same as the previous one.
Any help with this would be greatly appreciated. I'd rather not replace the materials on the many elements of the map.

Oh strange, from the error it seems to be from the prefab saving, maybe if they are prefab variants?
I am a bit in the dark here, can you share pictures or a package or something? This error comes from the saving system in Unity so something could be corrupted but its hard to tell what

Oh sorry, I forgot to mention. This issue happens with normal prefabs as well as prefab variants. I stripped things right back to iron out exactly where the issue is.
Here's a package with the issue still present in it. https://we.tl/t-gu2qML4OTy
This package was made in 2020.3.20f1 and requires a URP project.
Baking the lighting onto the prefab and then saving the scene (or trying to build, or put the prefab in a scene and saving that scene) shows this error.
I imagine the issue present in this package is on all of the materials that are in the package that provides the roads.
Thanks very much.
Edit: having tested some more with the project I created the package from it doesn't consistently produce the error anymore, which may make reproducing it an issue.

It seems to be an issue with the version of the materials you created, I wonder if you created these materials in a previous old version of the RenderPipeline because they are showing to be version -1 and the new Renderpipeline version checker fails with it. Definitely seems like an issue with those specific materials

Ahh, this makes a lot of sense.
The materials were part of an assets package that we bought and brought into the project.
To solve the issue I opened the materials in notepad++ and changed "version: -1" to "version: 4"
Thanks very much for the help and for creating the script!
