Windows 7 -> Windows 10 level problem?

First of all, let me just say that Windows 10 is TERRIBLE, and that I’m only using it to develop for UE4.

With that out of the way, I have installed UE4 on my W10 partition, and just tried opening my project file from the W7 partition. The loading went off without a hitch, until I found out that 10 crashes horribly when I open up the level with the most things in it. My second most developed level opens up just fine, but the only thing I could think that makes a difference between them would probably be foliage. They’re both pretty huge maps with painted landscapes, physics objects, characters, water, etc.

Does anyone know what the problem might be? I do have the Oculus Plugin enabled on both, as well as SteamVR, but should that make a difference? I would give you an error code, but it’s not throwing any?
