AJAX error when editing term content

@VladimirAus Sorry for the late response. Here is the requested information:

Version of my environment:
Drupal 9.5.2
PHP 8.0.27
Taxonomy Manager version 2.0.7 and 2.0.8

Steps to reproduce:

1. Go to Structure > Taxonomy and edit any vocabulary.
2. In the Manage fields tab, add general field like (Email) or (Link)
3. In the new field setting, select Unlimited, save field settings then save settings. This will add the Add another item button
4. Navigate to the list tab and add some terms to your vocabulary
5. Go to Structure > Taxonomy Manager and click on that vocabulary. From the terms list block on the left, click on any term. This will open the edit panel to the right.
6. Scroll down to the field you added and click on the Add another item. A spinning (Please wait) will show momentarily and then disappear without adding another field.

Please see the attached screenshot.

@VladimirAus Did you have the chance to look into the information I provided?
