A very large vocabulary will cause the parent terms selector in "Relations" to hang a taxonomy term edit page. The page will typically load, but only after 5-8 minutes have elapsed.
1. Build a large taxonomy list (95K entries should suffice).
2. Open the term edit page for one of these taxonomy terms.
Disable the parent terms selector function on taxonomy term edit pages for vocabularies containing more than "X" number of terms (perhaps 10K?). Parent hierarchies can still be selected through the Taxonomy Term overview page if needed.

This sounds familiar.
Yes, I found it, I think this was fixed in 🐛 Avoid loading all terms on the taxonomy overview form Needs work . That was committed to 10.2.x. And this is for Drupal 10.0, which is no longer receiving support. Can you upgrade to a supported version?
Changing to a support request.
