Fatal error using Niagara and C++ references to BP UE-74988

Just want to add comment for issue UE-74988.
Editor crashes, when I create Niagara Component in any BP-Actor, and create reference on it in C++ class from AClass or UClass.
If I setup settings for load in “Niagara.uplugin” to PreDefault - crash is gone.
And in PIE Editor works fine.
But if I build the game - build will compile, but game won’t work and show message that game cannot find some file without name of file.

I hope that information will be useful.

ps. Sorry for my bad English.
