Bedrock Realm Crashes: “Server not found” Bat

I have been digging out a large area of blocks around a wither skeleton farm in the nether. As I have cleared more and more blocks, I have started to get more and more frequent realm crashes (kicking out all players) and subsequent rollbacks varying from 20 seconds to 30 minutes. The crashes only occur when I am in the vicinity of the cleared area, and if avoided, the world runs fine without any crashes. It displays “Bat” on the error popup when the realm crashes. These crashes now occur within 1-2 minutes of arriving at this area around the wither skeleton farm, and I am unable to continue working on the project whatsoever.
