Issue with adding new content

I am encountering an issue when adding new content.

Steps Reproduce:

1. Installed the enabled module using Composer with the command: composer require 'drupal/content_freeze:^1.0'.

2: when trying to add new content it throws a warning, warning mentioned below.

Deprecated function: DateTime::__construct(): Passing null to parameter #1 ($datetime) of type string is deprecated in content_freeze_form_node_form_alter() (line 30 of modules\contrib\content_freeze\content_freeze.module).

I've attached an image illustrating my actions—installing the module and searching within the extended panel.
