Crash when using ConstructorHelpers on Niagara assets

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)

1. Create a Blank C++ project
2. Enable the Niagara plugin
3. Create a Radial Burst Niagara System called NewNiagaraSystem
4. Create a C++ AActor derived class named MyActor
5. Navigate to the MyActor source file
6. Within the AMyActor constructor enter the following: 

FObjectFinder (LoadObject/StaticLoadObject/FSoftObjectPath.TryLoad), e.g. ConstructorHelpers::FObjectFinder<UNiagaraSystem>Var(TEXT("NiagaraSystem'/Game/NewNiagaraSystem.NewNiagaraSystem'"));

1. Compile and Run the project from the IDE
2. Create an Blueprint from the MyActor class

Expected: An instance of NewNiagaraSystem is loaded

Result: The editor crashes
