Failed to compile default material WorldGridMaterial

You may need to reinstall/verify Unreal Engine. Unsure though.

I found a solution that worked for me. All I had to do was run the “Fix Up Redirectors in Folder” function on my entire “Content” Folder. Hopefully this helps someone else. I’m not exactly sure what created my “Fatal Error” to begin with though. It could be that I edited the project name outside of the editor, edited a file name outside of the editor, or deleted a project file outside of the editor. [28a6fd6fa6f4b67f34519e3f51565f24ec476929]
