OK so I figured this out but what’s happening is I was playing on my iOS version and every time I went to the nether it would lock up and not generate and not let me back into that map. After messing around deleting Minecraft reinstalling it on my iOS I tried signing out of my Microsoft account and creating a new map I was able to go to the nether in the new map with no issues. The second I sign back in to my Microsoft account I could not go to the nether of the world I just created or even load the map. I am a beta user on Xbox and windows 10 I went into my ID for Xbox and unenrolled from those programs, then uninstalled and reinstalled Minecraft on my iOS device and when I am signed into my Microsoft account I am now able to enter the nether.
