Little late to this but I had the same problem happen to me. I made a back up save just incase then went into repair mode, and it loaded me in. I didn't save when leaving repair mode (I don't know if it'll make a difference), but when you spawn in under spectator mode take note of where you spawn. When I loaded back in under regular survival I got through, but it dropped me from a slight height to were I took a little damage. Where it spawned me wasn't exactly where I crashed and I don't know if it is based on where you left/spawned, in spectator mode. So try to make sure that you are somewhere near the ground when leaving spectator mode, if you die, you can load up the back up and try again.
