Hello everyone, we’ve receiving on a newly installed WP Instance the error “Call to a member function get_method() on false” when using the plugin.

The instance is using following versions:

• PHP 8.3.9
• WP 6.6.2
• Plugin version is the latest one available

Apparently, the error does not appear when using PHP 7.x.

Steps to reproduce

1. Edit or create post in Gutenberg
2. Add Co Author block
3. Publish the post
   • On Publish, the post save results in a error
   • When opening the new post (which is saved even after the WP editor tells the user that the post could not be saved), the listed error is returned:
