Unreal Editor 4.21 and 4.20 are crashing often

I am experiencing a lot of crashes, generally when I try to access drop down menus, for anything really. Crashes occur most when editing materials or particle systems.

I have been experiencing these crashes on 4.20 and 4.21 builds, with the Niagara and VRay plugins installed. I have been experiencing these crashes without those plugins installed too however, so I don’t think they are the culprit. Sometimes, when I open my scenes, they just crash before they even start up.

I would really like to know what the issue(s) is/are. I have a great computer to work with, with two 1080s and an i7, 16GB ram, so I don’t think I am experiencing hardware limitations for the very simple things I have been trying to do.
