webprofiler没有在干净的symfony4项目上工作

I've got a strange problem going on with Symfony. Today I made brand new project using composer create-project symfony/website-skeleton gall command and right after installation, before doing anything in code I go to the website and the only thing that is said on webprofiler toolbar is "An error occurred while loading the web debug toolbar." I don't even get to see what kind of error is this.
The server I'm running is PHP v. 7.2.3, program is Xampp for Windows. I thought maybe this default starting page is bugged, so I made some test controller and the error is exactly the same.
Have you encountered such problem with latest symfony?

I would never figure it out myself, but adding index.php to browser address resolved the issue.

Much better solution is to use command

composer require symfony/apache-pack

As the .htaccess file is not included in the website-skeleton by default :)

Thanks for pointing me in the right direction guys!
