No, Admin Tools is NOT blocking HotJar.
As you can see in both of your screenshots, the JS file HotJar is trying to load is hosted on https://static.hotjar.com, not your site.
There are exactly TWO things which can block a file hosted on a third party server from loading in the context of an HTML page served by your site:
- A browser extension or browser feature which blocks that file for any reason e.g. tracker blockers (HotJar is essentially a tracker script, even though it only tracks your visitor for the purposes of click heat map and A/B testing).
- Content-Security-Policy (a.k.a. CSP) headers sent by your site, either through your .htaccess file or via a plugin. We have explicitly chosen NOT to integrate any interface to define CSP headers or use CSP headers in our software because they are complicated and error–prone. I know that Joomla 4 has such a thing built–in and the core contributor who implemented it also makes a Joomla 3 plugin which you may have installed.
