Loss of design with a parameter in the route [CI4]

Hi.
Most often this is due to incorrect $baseURL parametr in app/Config/App.php.
Show what you specified in this parameter and what url you get to load the stylesheet in the page header with and without a parameter.

Hello, I have configured the site with the .env file, do I still have to modify the config file?

Initially I didn't insert the base url in my links, now that I have done that everything is working fine.
