Hard to tell without checking web server logs but this is normally due to a PHP error.

Check your web server error logs for more information as to what is causing this. Could be as simple a thing as missing a PHP module.

You need to confirm your PHP version is PHP 7.2 or more version.

Google search this, I had the same on a fresh 2.3 install, and there is a line of code you have to add to one of the files. It fixed it for me

It's the core issue of Magento 2.3.0. 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));

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

This is a common problem with Magento, please follow the below steps to fix this:

Goto: xampp/htdocs/vendor/magento/framework/View/Element/Template/File/Validator.php

Old Code: 
public function isValid($filename) { $filename = str_replace('\\', '/', $filename); if (!isset($this->_templatesValidationResults[$filename])) { $this->_templatesValidationResults[$filename] = ($this->isPathInDirectories($filename, $this->_compiledDir) || $this->isPathInDirectories($filename, $this->moduleDirs) || $this->isPathInDirectories($filename, $this->_themesDir) || $this->_isAllowSymlinks) && $this->getRootDirectory()->isFile($this->getRootDirectory()->getRelativePath($filename)); } return $this->_templatesValidationResults[$filename]; }

Replace with New Code: 

public function isValid($filename)
{
return true;
}

I was facing the same issues and by following I fixed the issue, Hope it will work for you

Hello vineet_singh1,

Magento 2 CMS is a suitable platform for running an E-commerce business and can be administered using an admin panel. The admin is liable for the functionalities of the store. However, many users are facing the issue of a blank page in the admin panel after the upgrade or installation of Magento.

If you have recently upgraded or installed the latest version and encountered the Magento admin page blank issue, you must follow the steps below to fix the issue,

• Firstly, navigate to the following path:

/vendor/magento/framework/View/Element/Template/File/Validator.php:113

• Now, locate the below code,

protected function isPathInDirectories($path, $directories)
{
    if (!is_array($directories)) {
        $directories = (array)$directories;
    }
    foreach ($directories as $directory) {
        if (0 === strpos($this->fileDriver->getRealPath($path), $directory)) {
            return true;
        }
    }
    return false;
}

• Then, replace it with the below code:

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

If the issue persists, you can follow the ways mentioned below,

• Firstly, navigate to below file path,

#/vendor/magento/framework/View/Element/Template/File/Validator.php:114

• Then, locate the below string:

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

• Next, replace it with the following code,

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

• Lastly, save the file and refresh Magento 2 admin page.

PHP memory limit:

You will have to check the server settings and increase the memory limit in files php.ini, .htaccess, or index.php. 

• If you can edit server configurations, open the php.ini and set a memory limit of 756M with the following command:

ini_set('memory_limit', '756M');

• Finally, flush the Magento cache using the below command to apply changes,

php bin/magento cache:flush

I hope the ways above help you to solve the Magento "Blank page at login admin" issue.
