Editor Crashing when opening level, not sure why

My Unreal Project crashes and I don’t know how to stop it (Version 5.2.0). I Was editing in a UI Blueprint (one that I cannot show because it crashes the editor), and I created a boolean variable by the name of “A1Broken” or something of the sort. As soon as I finished typing the name in, Unreal crashed, and i was given this as my error.



I typed in the “Unhandled Exception” part into Google and there were literally zero results.
Thankfully, the given level is not the one the Engine starts on when opening the project, so it doesn’t crash immediately. However, it crashes if I try opening the level, or opening the blueprint where I made the variable when it crashed. I am able to open the other UI Blueprints used in that level (while still in the first level) but trying to open the select one where the crash occured crashes it again, resulting in the same error as before.
I’m not sure how to fix this, so I was wondering if any of you might.
