I believe it's your plugin because I deactivated all of ours, then enabled them one by one, and activating yours brought back the problem. On line 134 of wp-content/plugins/autoroyal/includes/admin/class-autoroyal-admin.php, you include your own version of jquery-ui and commenting out that line corrects the issue.
That same type of inclusion exists on line 120 of wp-content/plugins/autoroyal/includes/public/class-autoroyal-public.php. Which I assume can and will cause other conflicts.
Maybe just add the internal jquery-ui as a dependency for your script(s) that rely on it?
