With the V5.5 of Wordpress, we have seen more jQuery issues. Here are some things to investigate if you HIPAA Plugin is not working correctly:
1. The first thing to do is to check this article and the associated plugin: Wordpress V5.5 Upgrade - jQuery issues
2. Check your security and firewall plugins on your server. For example, ModSecurity may have higher security that blocks calls (usually causing 404 Console error). Typically it is with ../wp-admin/admin-ajax.php module that can be whitelisted
3. Performance plugin settings like w3tc or super cache, possibly minifying and compressing JS which may cause issues
4. CDN (Content Delivery Network) settings possibly minifying or compressing JS
5. Start disabling plugins to see if issue resolved (this is also within step 1)
