After the Update to WordPress 5.4, Site Emails are not sent !

I have recently update my group of sites to WordPress 5.4. But i have a problem. Before the update, all comments of the posts of the Blogs, were sent to the Admin Email. Before the update of WordPress 5,4 all comments of the posts of the blogs, were sent to the Admin email. But now, after the update of WordPress, in all my sites, all comments are not send to the Email Admin any more. My Admin Email not received the comments of the posts of the Blogs any more. I suspect that WordPress don’t send any types of email any more ! Have someone received a similar error ? Can someone help me ?
