CIL "Failed to resolve assembly" Linker Error, need help indentifying

I’m getting the following error when I attempt to build my project:

Fatal error in Unity CIL Linker

I’m unsure of what is wrong.

I had a similar issue when my project filepath contained special characters.

Are you able to build a new project with the same filepath?

Could you try moving your entire project to C:\UnityProjectNBCC\ and see if removing the spaces resolves it?
