Hello, I'm currently experiencing an issue with my world where it is constantly crashing after playing for a short period of time.

I have narrowed the probable cause to a couple of instances: First, I noticed that it happens when the autosave is conducted. This observation is due to when I reload the world after the crash the previous save is loaded. In summary, anything I do from when I loaded the world to the crash is forgotten. Or I've noticed that the crash occurs when either my friend or I get into a bed. Of course, this could be coincidence, but the amount of times this occurs leaves me suspicious. I fear that it is most likely something to do with the save and I hope there is a fix. I should also add that I was playing with a friend when the first crash occurred. They were a good distance away from me as well. Currently, the world size is about 18.3 MB. The listed storage fluctuates between each crash. For example after the first crash it may say 16 MB, then after the next crash it will say 0.01 MB for world size.

I have spent a lot of time on this world, and it would be amazing if there is a fix. If anyone has this same issue please let me know. I have already tried numerous methods to attempt to resolve the issue.

Failed Resolution Attempts:

1. Delete unused or unneeded space such as worlds and texture packs

2. Copy the world and restart from back up 

3. Check for corrupted data in switch settings (Note: no corrupted data found)

4. Re-downloaded minecraft without removing saved player data

So far after redownloading it has been the most stable, but it still crashes the world on start up of the world occasionally. I haven't started it up since the one time I did after the reinstall because I fear it could possibly corrupt the world.

It should also be noted that the world started with the Old Minecraft Texture Pack from the marketplace installed. The pack was later suspiciously missing when the world crashed. 

 Thank you for your time, it would be amazing if we can find a solution without deleting the world!
