Your issue is that WordPress does not have archive for all posts in specific taxonomy, only archives for posts in each term of that taxonomy.
In your CPT registration you can set 'has_archive' => 'quizzes'
so that post type archive slug is different from singular slug. However I am not sure if that will work properly when your taxonomy is also using that slug for term archives.
