🐛 | Drupal core | Avoid loading all taxonomy terms on taxonomy term edit page for very large vocabularies

As a temp fix we disabled the parent selector form in a custom module:
/**
* Implements hook_form_FORM_ID_alter().
*/
function taxonomy_fix_form_taxonomy_term_form_alter(&$form, FormStateInterface $form_state): void {
$form['relations']['parent']['#access'] = FALSE;
}
