Crash when LAN co-op session

Dear developers,

The latest beta update became available for me last day on Google Play Store. And I updated to it on my OnePlus 6 and Samsung Galaxy S20 Ultra (Both are Android 10) and my two computers, a shaky aged laptop with 8GB RAM and an up-to-date desktop with 32GB RAM. (Both are using Windows 10 21H1)

It worked well in LAN co-op mode for a few minutes when Cliffs and Caves toggle was on, and crashed in few minutes unexpectedly. I tried to rebook all devices I have, but it didn't work.

I was thinking it was caused by unstable beta features and disabled all experimental features in a new world, a fatal error occurred and resulted in the host (my desktop) to reboot. I haven't seen anything worse than this in Minecraft. Hope the instability will be fixed soon.
