Fatal error on project start up UEFN

I have a main project that has multiple “Project Locations” (duplicates) but all of these connect to the main project. When I try to load any of these duplicates that are affiliated with this main project, UEFN immediately crashes with the following message: Fatal error: [File:D:\build++Fortnite\Sync\Engine\Source\Runtime\RHI\Private\PipelineStateCache.cpp] [Line: 477] Shader compilation failures are Fatal.
I would appreciate any and all help on this, thanks.
