Hello, @yahya,
Ok if you find it difficult, then please try to update the Theme manually: https://xstore.helpscoutdocs.com/article/63-theme-update
If still, you will find it difficult then please take the complete backup of your site and then share your site WP Admin Credentials and also the CPanel Credentials as well with me in a private content area of this topic so that I’ll update the theme for you on your site and make a video for you as well for the future.
Regards 8Themes Team.
