Crash in packaged EXE, but never in Editor

Hello everyone,

As in the title and category, I am developing a VR experience, and wish to have an EXE to show around.
Unfortunately, the packaged version tends to crash (roughly 30-40% of the time) within 45 seconds after a certain level transition. If it doesn’t crash then, it runs fine. This crash never occurs in the editor, and I haven’t the slightest idea why.
Packaging the project from other computers made no difference.
I’ve looked through crash logs and memreport, but I don’t have the expertise to properly interpret them.
The relevant part of the crash log is attached here.
Any insight you can give would be greatly appreciated,
