Gaps in Overworld

Since my last start up of Minecraft Bedrock (Xbox played on series X) I have big gaps in my world. I've made a screenshot for better context concerning the problem. Is this something what your supportteam can fix?

First I thought it was a visual bug so I tried to row the sea, or at least what was the sea earlier on. But I literally fall of the world.

 

I noticed thes big gaps at multiple places in my overworld. Even bedrock isn't visible.
