Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
The admin-ajax.php file is used by WordPress to refresh data on pages without reloading the pages. Without that, you would need to hand-load the files you need, which is a complicated process.
In short, it’s used just for the AJAX calls on the website, which pretty much all plugins and themes use.
However, I checked your website’s robots.txt file and the setup for robots.txt is perfectly fine as it should be. Google seems to be trying a direct crawl of the URL. Since there should be no pages at that URL, the page crawler shouldn’t find any. So in this case, a 4xx status is entirely fine and makes sense. Therefore, you can avoid fixing Blocked due to other 4xx issue for this URL, as technically it is not broken.
Don’t worry, a 4XX error for this URL will not affect your indexing and ranking.
Meanwhile, you can wait for a re-crawl of your website and hopefully, the issue should go away.

Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
