After installing magento 2.3 admin login page cant open properly

Question

After installing Magento 2.3, When I am trying to open the admin panel login screen is blank and my console contains an error as shown in the image. if anyone has a solution then please let me know.

Answer 1

Find: /vendor/magento/framework/View/Element/Template/File/Validator.php:139

find:

foreach ($directories as $directory) {
    if (0 === strpos($realPath, $directory)) {
        return true;
    }
}

Replace with:

foreach ($directories as $directory) {
    $realDirectory = $this->fileDriver->getRealPath($directory);
    // and replace `$directory` with `$realDirectory`
    if (0 === strpos($realPath, $realDirectory)) {
        return true;
    }
}
