I am sorry to hear that things are not going smoothly.
Try the following steps:
1. While “Restoring Database” leave the plugin running for another 15 minutes.
2. After 15 minutes, open another tab of your website to see if the homepage was imported successfully or if there is an error.
If you receive a 500 or critical error, please edit your wp-config.php file and set WP_DEBUG to true, then refresh the homepage to see the error.
This may assist you in determining the problem. Otherwise, you can share the error with me and let me know what PHP version you are running so that I can assist you in resolving it.
