I faced same issue and resolve following below steps:

1. go to the app=> Config => Boot => production.php in your project
2. Change the ini_set('display_errors', '0') to ini_set('display_errors', '1') above will show you the error detail then do the following:
3. Open [xampp_folder_path]/php/php.ini to edit.
4. Search for ;extension=intl and remove the ;.
5. Save the php.ini file and restart Apache.
