New users don't have password... user_hash=NULL

Hello.
I have problem. New users who created from admin, don’t have password, in DB user_hash=NULL.
If i change password from command line, all good:
UPDATE users SET user_hash = MD5(‘SECRET_PASSWORD’) WHERE user_name = ‘USERNAME’;
But in web interface from admin, passwords wont changed.
If i try change admin password from web, nothing happend, password not change.
If i create new user and write password to him from web, then in DB i see: user_hash=NULL.

SuiteCRM 7.11.0
PHP 7.3
PS: Sorry for my English.

There is a link to gitHub with a patch for this error in the following forum thread:
https://suitecrm.com/suitecrm/forum/feedback/21522-bugs-in-7-11-0-users

After i update Users.php file i see in logs, new password write to DB but “Hook called: Users::before_save” and DB overwritten with old password:
