That’s a known issue with the Incremental compiler. It has been going for quite a while now.
Take a look at this thread: https://forum.unity.com/threads/unity-incremental-c-compiler.523993/
I made a few comments there with a workaround to disable the weaver by patching its DLL.
In my project, I delete anything that uses a NetworkBehavior so it won’t trigger the UNet weaver.
