After facing same issue looking into the error area. 

found a solution and it working for me.

...\vendor\magento\framework\View\Element\Template\File\Validator.php

A function isPathInDirectories added a line

$realPath = str_replace('\\', '/', $realPath);

or refer below code function  

protected function isPathInDirectories($path, $directories)
{
    if (!is_array($directories)) {
        $directories = (array)$directories;
    }
    $realPath = $this->fileDriver->getRealPath($path);
    $realPath = str_replace('\\', '/', $realPath); // extra code added
    foreach ($directories as $directory) {
        if (0 === strpos($realPath, $directory)) {
            return true;
        }
    }
    return false;
}

It's working.

This issue come because of space before PHP start tag of class file, just removed white-space to resolved:

<?php 
namespace Magento\Framework\View\Element\Template\File;

to

<?php 
namespace Magento\Framework\View\Element\Template\File;

 so always keep PHP start tag in first line.

@aman10900 Hope this will help you.

Thank you for the solution.

I am using Magento version 2.3, and was presenting the error: "main.CRITICAL: Invalid template file: 'C: /cursomagento/vendor/magento/module-theme/view/frontend/templates/page/js/require_js.phtml 'in module:' 'block name:' require.js' "

I was able to resolve with your help.

Thank you.

Hello,

After including the line, it's good for the admin screen.

If i click on "Create an account" i will have "Luma" and others informations on the screen
View2.png
Could you tell me if it's because i have a magento version without sample ?

Thanks
Bruno.

Thank you so much! After 3 full days of trying all the other stuff, changing permissions, changing WAMP to XAMPP, changing PHP versions, changing PHP versions of local machines, trying Windows CMD and Linux CMD, Composer install...  This finally did the FKN trick! Can't thank you enough, even took the time to create an account to reply... think that says it all
