Thank you for your report!
Crashes such as these are logged automatically, and will be looked into further by the development team.
If you feel this is still a valid issue then please comment, or create a new ticket following the Issue Guidelines including steps to reproduce the issue.
If your world is crashing, and you have a copy of the world available, you might like to make a copy of it available here for investigation:
On Windows 10 you can use the Export world feature.
On Android or iOS you need to use a file explorer to navigate to Device storage > games > com.mojang > minecraftWorlds
On Xbox or Switch the only way is to upload it to a Realm, and then download the world on Windows 10 or Android/iOS.
If the world is larger than 10MB you can upload the world to OneDrive or a similar file sharing site, and then share the link.
