Hello there.

I Just update Engine to version 4.21.1 from Launcher today，then suddenly something goes wrong.
Whenever I edit the exposed Niagara variable in blueprint Details panel, editor crashes all the time.

As show in the figure below, when I editing User.LifeTime, as long as press enter or edit box loses focus, editor will crash.

I try to clarify if I did something wrong, then I create a empty Niagara Emitter and Niagara System from scratch，but still no luck。

I’m still trying to figure out the problem, any help is appreciated,

Thanks!
