Sage 300 not responding at the Change Password stage

After upgrading to v2023 and SP3, when a user tries to login , it askes for the password to be changed "Password change required". On the Change password screen , after entering the old password , new password and confirming the new password, when the user clicks on the "OK" button ,  nothing happens. What is causing this issue ? As the Administrator I have also tried to reset the users password and ask them to change it to reset it at 1st logon but at the Change password screen, the same issue persists . What is causing this issue ?
