I just checked your problem with our team and one of our team members Arlind told the that he had this same problem once with some users from Japan and China.
Arlind replied that user with this comment:
Editing core wordpress files is not recommended because they will change after you update WordPress to a newer version. I'd like you to contact your host and ask them what is blocking admin-ajax.php to execute?
Our theme uses this action on AJAX to save theme options:
They can probably help you to discover the problem, there is nothing wrong in theme files because the theme options work properly on all WordPress sites as they are properly programmed in the "WordPress way" however in your case it is not working to save theme options
And the user replied:
The cause was "WAF" which is the setting of the server.
I disabled this. It worked on this alone.
Please contact your server administrator about this and they should know what is the problem and solve this problem for you too.
你好
在实验室的主题选项中，完成设置后无法保存。
“保存所有更改”的标签无论如何一直保持转动并且完全没有响应。我每天尝试了无数次，但没有一个幸存。因此，购买后无法使用。请告诉我怎么了。谢谢！

Our theme uses this action on AJAX to save theme options:
"of_ajax_post_action"

Testing one core AJAX action it works:

hi Ylli
Thank you very much for your reply！ It turned out to be the reason of WAF! Thank you very much. I've worked it out.

Happy to hear that
Have a great day and stay safe!
P.S: If you like the theme, it would help us a lot if you could give us a five-star rating on Themeforest from your Downloads tab.
A huge thank you from me and Laborator in advance.
