Iron golem dont spawn

Hi sir,

I'm playing on the 1.16.40 bedrock french edition with Windows , everything is updated.

I revived and enlarged an abandoned village.

The village has about 45 beds and more task blocks, many are near the bell
Villagers have potatoes, corn, carrots with 4 fields and get together every days. They have children.

But iron golem never spawn. I don't understand why, everything looks good.

I can't send you the compressed file of 13.3 Mo

Best regards.
