How do I fix this crash?

Hey,

in UE4 “4.25.1” I am having the issue where I can not add user parameter into Niagara system without a crash I am having the same issue as in “UE-93845” I tried the fix which is in NiagaraSystem.cpp and tried running “4.25.1” again to check if it is solved and I am still getting the same crash so I am not sure where is the problem nothing changed after applying the couple line of codes in the fix commit. I see there are like 8 people voted with solved when it did not solve mine. so if there is a fix could you please provide it to me?

Thanks in Advance,
