Magento 2.4.1 does not work properly homepage and login page for admin panel at localhost

[apostolis_dimit]

I decided to try Magento 2 so I tried to download the open-source version. After a lot of effort, I made it and I install Magento 2 on my localhost. The problem is when I go to the homepage I see this(1) and when I try to login I see this(2). I tried some possible solutions from the Magento forum and I changed some lines in the di.xml file and Validator.php. The change in the Validator file works in some parts (appear the login form but there is another problem I can not log in with the username and password, which I am sure are correct). Does anyone else have the same problem?

My PHP version 7.4.11.

I use xampp for localhost.

You need to replace

$realPath = $this->fileDriver->getRealPath($path);

With 

$realPath = str_replace('\\', '/', $this->fileDriver->getRealPath($path));

In 

C:\xampp\htdocs\magento\lib\internal\Magento\Framework\View\Element\Template\File\Validator.php
