This is pretty much what I was looking for. Can't believe I missed it. Thanks! Fingers crossed that it's fixed in time for release.

@Graphics and Games Engineer I also wanted to mention that the problem where the other simulators don't work when the visionOS one is open seems to have been fixed in Xcode 14 beta 3 (15A5195k) and macOS 14 Sonoma beta 3 (23A5286g). I'll update the feedback with this information too.

@Graphics and Games Engineer Thanks for taking a look at it. If it's possible for them to answer this question: Are there any plans to add the missing Metal features to the VM graphics driver, or modify the simulator so that it can work without the missing Metal features? If not, it would be nice to have a message letting the user know that the visionOS simulator doesn't work in a VM, because it seems like a few other people are confused about this too.

Sure, I will do that and post the feedback ID here.
