Well, it got fixed, I have NO IDEA how, but it did. I was trying to record what happens if I try to run as administrator, and or save to a different location. it did the same thing, then, my screen recorder crashed, and I had to redo the video several times. After a while, Epic just for some reason decided to play nice, and so did Camtasia, so, no more crashes for now. Putting together a long video of everything I recorded during that time.
Edit, was trying to upload video (under file size limits), but it was taking a while, so I decided to test again, and what do you know, the problem’s back. It only seems to do this on Epic, as, I can open/save just fine in other programs. Hmmm.
