Error: You did not sign in correctly or your account is temporarily disabled

I create a user (from the magento panel) for my store, and the link to set the password is sent to the email, the user has set the password.

After a few hours (6/7 hours) the user is no longer able to log in with the password and presents the error;

You did not sign in correctly or your account is temporarily disabled

I checked the “customer_entity” column and the password_hash field is empty!

I don’t understand how this is possible.

Magento 2.4.2

Thanks
