    Please follow instructions below. I hope it will resolve your issue.

    Just go to vendor/magento/framework/View/Element/Template/File/Validator.php and find function function isPathInDirectories line 138.

    Replace: 

    $realPath = $this->fileDriver->getRealPath($path);
        foreach ($directories as $directory) {
            if (0 === strpos($realPath, $directory)) {
                return true;
            }
        }

    With:

    $realPath = $this->fileDriver->getRealPath($path);
        foreach ($directories as $directory) {
            $directory = $this->fileDriver->getRealPath($path);  //Add this line.
            if (0 === strpos($realPath, $directory)) {
                return true;
            }
        }

    I am also facing the same issue while installing Magento 2.3.3 in my localhost – XAMPP Server. It’s successfully installed, but when I opening the admin panel, it appeared a blank screen like the below image. Admin Panel

    The Solution is:

    After that, I changed the code like below.

    Go to this Path: ..vendormagentoframeworkViewElementTemplateFile then Open this file Validator.php

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

    Replace to $realPath = str_replace(”, ‘/’, $this->fileDriver->getRealPath($path));

    Image for reference to change the Validator.php file

    Now Admin Panel will appear successfully.

    Admin Panel appeared, but the issue is Magento logo does not appear on the login screen. After logging the admin Admin Panel, Icons don’t appear on the dashboard also its continuously loading like the below images Icon Don’t Appear

    The solution is:

    Go to this Path: ..appetc then Open this file di.xml

    Then search this line MagentoFrameworkAppViewAssetMaterializationStrategySymlink

    To Replace the line MagentoFrameworkAppViewAssetMaterializationStrategyCopy

    Check this image for replacing the code & Make sure the code should come like this image

    Now Go to the Admin Panel and Refresh the page. It’s Successfully working without issues. All icons have appeared also Logo is appeared.

    Admin Panel Sucess image

    Now Go to Client Area, if you update sample content, the page looks like this image Client Page with Sample Content. Otherwise, it will appear like “CMS homepage content goes here”.

    Everything is working good.

    I hope it will use to solve this issue.
