Editor crashes in PIE after updating project to 4.16.1

I just updated my project from 4.7.6 to 4.16.1 (I made a backup of course) and for some reason whenever I try to play the game in the editor, it will freeze for awhile, then crash. Has anyone else had this issue?

Another thing to note is that when I packaged the updated project and ran it, the packaged game didn’t crash. But instead, it couldn’t open any levels whenever the Blueprints told it to. (It would always open to the default level) This isn’t or shouldn’t be a problem with my project, as it worked fine (both in editor, and when packaged) before updating.

I am also suffering from this issue and whenever I hit the play button it crashes

Same problem here. Any help?
