For Magento 2.3 there is issue with "\"
/vendor/magento/framework/View/Element/Template/File/Validator.php In above file find
$realPath = $this->fileDriver->getRealPath($path); // approx 114 line
Replace with
$realPath = str_replace('\\', '/', $this->fileDriver->getRealPath($path));
I hope this will help you.
It's the core issue of Magento 2.3.0 with Windows because Windows uses "\" as a separator. To fix this issue you have to change the code in the core file of Magento.
Go to path /vendor/magento/framework/View/Element/Template/File/Validator.php In this file find
$realPath = $this->fileDriver->getRealPath($path);
Replace with
$realPath = str_replace('\', '/', $this->fileDriver->getRealPath($path));
