Answer 2

This is the problem with windows. Windows uses "" as separator, the array "directories" contains entries with "/" as separator, so the check will always fail.

So you need to fix this by replacing the separator in core file:

Magento\Framework\View\Element\Template\File\Validator

function isPathInDirectories replace below code in isPathInDirectories function

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