When using the ConstructorHelpers templated function, FObjectFinder, with Niagara assets, the editor crashes.
Tested in 4.21.2 (CL - 4753647), 4.22 (CL - 5660361), 4.23 (CL - 5806860)
FObjectFinder (LoadObject/StaticLoadObject/FSoftObjectPath.TryLoad), e.g. ConstructorHelpers::FObjectFinder<UNiagaraSystem>Var(TEXT("NiagaraSystem'/Game/NewNiagaraSystem.NewNiagaraSystem'"));
Expected: An instance of NewNiagaraSystem is loaded
Result: The editor crashes
