Unity compiler error goes away on restart

Hi I am working on a project where assets are copied into Unity’s assets folders ( not scripts, but just Unity assets like textures). The reason for this is to facilitate switching between different games that only differ in certain assets. I do this with a method in Initalizeonload But the problem I have is that sometimes when someone else is trying to pull my changes in Git, they get compiler errors that goes away on restart. What could possibly cause such a thing? Oh fyi, the compiler errors do not happen if it’s a fresh clone of the project. It just happens when someone pulls in my changes
