I figured it out! I remembered something that changed before it started crashing. I changed my default program to open image files to "Photos" which is a photo viewer that is part of Windows 10. If I change it to something else like "Windows Photo Gallery" it doesn't freeze!
The engine is crashing while I'm just viewing files in the import menu. For example, I'll try to import a frame image for an actor's animation. By simply scrolling the import window down, the import window becomes completely unresponsive. It seems to be tied with certain files being displayed in whatever folder I'm importing from.
Edit: When the attached image is scrolled over in the import window, it becomes unresponsive.
It happens with more than just this image, I've tried re-exporting it and converting. Nothing works.
