A broken shader file can stop the compilation process entirely. Deleting the cache forces the engine to rebuild it. Navigate to the folder where you installed the mod kit. Locate \Engine\DerivedDataCache .
According to community feedback on Unreal Engine, the initialization process often pauses because it is processing a huge amount of data. hello neighbor mod kit stuck at 45
