Game crashes when using commands or bed after rain and night starts

I was playing Minecraft bedrock edition on my iPad (single player) this world had many add-ons and custom NPCs. As normal, the sun went down at the usual Minecraft time and it started raining. This was a creative world, so I simply typed in the command: “/time set day.” right after, it automatically crashed me out of the world and sent me to my iPad Home Screen. I thought it might’ve just been a glitch with my iPad so I went back in the world and used /clear weather. Once again, it crashed me out of the world and sent me to my home screen. So I made a different world with the same add-ons and NPC but everything worked fine. So I went back to the original world and tried to sleep in a bed. When I clicked on the bed the world crashed again! Then I tried to use different commands and place different blocks like teleportation commands and placing wood. It all worked so instead I tried to just wait out the night but I had waited for around 25 minutes, which should’ve been long enough for it to become day again and it still was midnight. I started getting a little bit scared. I tried leaving Minecraft and closing all my apps. after I did that, I rejoined the world to see if my iPad might’ve just been a little bit glitchy because of all the apps I had open. The same problem occurred. I checked if it was on multiplayer just to see if one of my friends was trying to prank me. It said I was the only one playing on the server. I showed my family (who are pretty good with computer science) and even they couldn’t explain what was going on. I was getting increasingly scared so I deleted the world. the same problem never occurred in any other world. I know this sounds like a made up scary story but I promise this really did happen. I hope you can get to the bottom of this and find out what was happening.
