Plugin No Longer Creating User Accounts After Registration

Everything has working fine all year until this month. On our User Registration page, after the user signs up and pays, the plugin is no longer creating the user account for the user. We are using the “Simple Membership” plugin aka “WP Membership”. with a registration form created with Forminator. We have contacted Forminator and they have checked and said the user is not with their plugin. Not sure what is going on but the user accounts are no longer be created at registration. Any help with this would be greatly appreciated. Thank you.
