Javascript Crashes when loading existing Tags in a Post

    Hi,
    We have a problem on a website with a lot of Terms in the post_tag Taxonomy.

    The browser tab crashes whenever I write something in the tag input field.
    The ajax call (/wp-admin/admin-ajax.php?action=ajax-tag-search&tax=post_tag&q=texthere) is executed correctly and in a timely manner.
    The problem is evidently the javascript handling the creation of the list of matching tags.

    This only happens with the Classic Editor (all versions from 1.0 to 1.6.2) on WordPress version 5.6 and above. I can confirm that it works from 5.4.2 to 5.5.5.

    All the tests where performed with the twenty twenty theme and only the classic editor plugin active.

    Can you please help?
    Thank you!
