Xbox dev mode fails to launch

I've been using dev mode at for a while with no real problems. I brought my console over to my brother's house so I could show people the game I've been working on,but now suddenly my console will no longer boot into dev mode.

If I unplug the console for a minute it will boot into retail mode, which seems to be working fine. But when I activate dev mode, it resets, but then gives me a screen that says:
"Something went wrong"
with an option to restart or troubleshoot, and a system error of E200 00000074 00000000

It constantly hits this error no matter how many times I try to reboot. I can unplug it and boot it back into retail mode, but it simply will not boot into dev mode anymore. I don't want to try the option to reset the console because I suspect it would delete my game, and I didn't bring my laptop so I can't upload my game back onto my console without going home.

Any idea what the problem is here? Is this just how dev mode acts whenever I am on a different network than where I installed the game from? Is there some update in the works? Why can't I get into dev mode?

Other info: My game is made in Unity, so I find it doubtful that something in my game is causing this problem. At most, I installed a second Unity game to my xbox, but I doubt that would be related.
