Upon your insistence I took a VERY close look at it.
I disabled my local server on Windows 10 and removed the Apache and MySQL servers to avoid any conflicts.
I download and installed the latest version of XAMPP (no version number stated on their site) with PHP 8.0 .
I confirmed that it works.
I created a new database named joomla with a user joomla with password joomla having all privileges for it.
I created a new folder called joomla using Windows Explorer under the directory c:\XAMPP\htdocs, i.e. I now have a directory c:\XAMPP\htdocs\joomla
I downloaded and installed Joomla 3.10.5 using the Brochure sample data into the directory c:\XAMPP\htdocs\joomla and the database joomla with username joomla and password joomla. It installs just fine.
I confirmed that the site works properly as-is, i.e. accessing http://localhost/joomla/
shows me the site I just installed.
I downloaded and installed Admin Tools Professional 6.1.4 on this site.
I used the Quick Setup Wizard using its default options, without changing a single thing.
Trying to access http://localhost/joomla/
works just fine, showing the site, the exact opposite of what you described.
Likewise, trying to access http://localhost/joomla (WITHOUT the trailing slash) redirects you to http://localhost/joomla/
and the site displays just fine.
Accessing http://localhost/joomla/index.php of course works just fine.
Further to that, trying to access a random directory or file such as http://localhost/dodo or http://localhost/not_there.html results in a 404 error page. It does NOT redirect to http://localhost/dashboard which is the exact opposite of what you described.
As a result and upon VERY close examination I conclude that your issue does not exist with the steps you have provided for replication.
The only way your issue could be experienced is if you had somehow set up a redirection from your site's root to the XAMPP root (https://localhost/). This does not happen automatically. I tried a few more different ways including creating the site afresh and accessing it over HTTPS (so that Admin Tools tries to use HSTS) to no avail. You need something third party to trigger this redirection and this something is not Admin Tools itself.
Another possibility would be you using an older version of XAMPP which does something weird instead of just redirecting http://localhost/ to the dsahboard but given that I have never heard about your issue as described or any other similar problem with any version of XAMPP I am far more inclined to believe that your problem has to do with something specific to your site, not Admin Tools or XAMPP itself.
Therefore I consider this issue self-inflicted due to site configuration.
