Unreal engine start new projects bug

I got a warning on when I opened a project that said:
Ensure condition failed: Using a global shader permutation
of FTSRRejectShadingCS which hasn’t been requested
for precaching at runtime. Check the implementation of
ShouldPrecachePermutation on the global shader and make
sure all required or development only permutations are
requested for PSO precaching

Please help me
