June 10th, I moved to the ender world to grow a tadpole into a green frog, but it suddenly shut down. After reconnecting, the iron golems started not appearing on the iron farms that were working properly. So I moved and rebuilt the iron farm, but the result was the same.

Steps to Reproduce:

1. Create an iron farm
2. Wait for the iron golem to appear. 

Observed Results:

Iron golems do not spawn.

Expected Results:

Iron golems must spawn on iron farms.

I made an iron farm based on this video. This iron farm also works fine on 1.19.

Notes:
