Error in Drupal 10 - Drupal\Component\Plugin\Exception\PluginException: Plugin (entity:taxonomy_term) instance class "Drupal\taxonomy\Plugin\views\argument_validator\Term" does not exist

I think I found the issue, thanks to ChatGPT. In product_taxonomy_filter.views.inc, line 38 says:

$plugins['entity:taxonomy_term']['class'] = 'Drupal\taxonomy\Plugin\views\argument_validator\Term';

However, the Term file does not exist in D10 core; TermName exists. Therefore, I changes that line to:

$plugins['entity:taxonomy_term']['class'] = 'Drupal\taxonomy\Plugin\views\argument_validator\TermName';

And that allowed me to access the settings for the contextual filter.

Made a patch with the change suggested in #2. Manually testing and not seeing any issue in 9.5 or 10.0.7.

That solution doesn't work for us (Drupal 10.2) because all taxonomy terms on the website are showing a 404 Not Found page now.

Here's a new (temporary) solution
