Would this htaccess code prevent a link from leaving the website?

On this wordpress page https://stealthvideo.com/test/ the 'click here to view demo' link just under the header is supposed to go to https://cctvconnect.com/demo/cameras/grid
Instead, stealthvideo.com is being inserted in that link so it fails.
I checked the link, there is not stealthvideo.com in the link. I asked the wordpress theme developers, they said if the link is correct then it's probably an htaccess issue. I pasted the htaccess code into chatgpt, it said that code would not prevent a link from 'leaving' the website.
This is the htaccess code:
# BEGIN WP Rocket

# END WP Rocket

# SGS XMLRPC Disable Service
<Files xmlrpc.php>
order deny,allow
deny from all
</Files>
# SGS XMLRPC Disable Service END


#Begin Really Simple Security
Options -Indexes
#End Really Simple Security
# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

# SGO Unset Vary
Header unset Vary
# SGO Unset Vary END

If anyone knows whether that code would prevent a link from leaving a site, somehow inserting the domain in the front of the url, please let me know. Any feedback is appreciated, thank you.

I figured it out, answering here in case anyone else has this problem. A clients wordpress site had some code in the htaccess file that was preventing outbound links from working. The plugins were no longer installed. I copied an htaccess file from a staging site on the same hosting and that fixed the problem.
