Crash in End with villager

I was in the End in creative, trying to make some villagers in some houses. I was curing zombie villagers that I had spawned with spawn eggs, and had previously cured 4 (four) in the over world and 1 (one) in the End, but once the second zombie villager in the End was being cured (a few minutes after giving the golden apple), the game crashed. Any time I try to open that world now, Minecraft crashes, and I have confirmed that i can open other worlds.
And just to make sure it is obvious, I am on my Android phone, using the Beta 1.16.0.64 version.
