Seems your project is crashing while building shaders

void UMaterialInstance::CacheShadersForResources(EShaderPlatform ShaderPlatform, const TArray<FMaterialResource*>& ResourcesToCache, EMaterialShaderPrecompileMode PrecompileMode, const ITargetPlatform* TargetPlatform)
{
	UMaterial* BaseMaterial = GetMaterial();
#if WITH_EDITOR
	check(!HasAnyFlags(RF_NeedPostLoad));
	check(BaseMaterial!=nullptr && !BaseMaterial->HasAnyFlags(RF_NeedPostLoad));
	UpdateCachedData();
// more code.....



Remarks

Caches shader maps for an array of material resources.
