Entering End Portal causes crash, Realm disconnection and rollback

Greetings. Upon trying to the enter the end portal, my character did not go through but instead sat on the starry scene. Suddenly everyone in the realm, including myself, was disconnected from the server. When we logged back in, the server was reset to a few minutes prior - assuming the last backup save. I went to try to enter the end portal again and the disconnection occurred again.  

 

As far as we know, we weren't spawning enough entities to cause the crash. There was only 4 people online at the time and they were doing their usual builds and such. We truly are u sure why this is suddenly happening as I went in and exited the portal just fine earlier today. 

 

Here is a link to the occurrence. I was streaming at the time and was able to save the footage:  https://clips.twitch.tv/SpoopyDirtyCormorantANELE-bZMPTFYqAK2KhpV5

 

No I have no idea why the link says spoopy whatever. Twitch being weird i suppose. Also the version is whatever the most recent version was released in vanilla bedrock.
