Ah that would do it 🙂. I forgot that I had exported the world, aka copied, in an attempt to change the mode to creative. I bet that did it. Good job!

Platform: Xbox One X
I did nothing other than trying the next day.
I reported hitting this 2 days ago, however after giving up trying to load my world and going to bed I tried again the next day and was able to load just fine. My character was no longer in bed. I don't recall downloading a patch with a fix for this, so I'm unsure how 24 hours later I was able to simply load into the world without the Leave Bed/Open Chat button issue.
Same issue. I'm on Xbox One X with the Nether Update installed today. Can't load into our world because we're in bed which results in a hang of sorts and then unexpected termination back to Xbox home screen. No workaround found.
Can you copy the world? That’s what did it for me.
