You can refer google for some suggestions but you will need to hire someone to get the issue fixed if you need some more from here as the issue may come from anywhere.

The issues is resolved. We were using a plugin that support Elementor in design. we deactivate the pluing and run the crawler. All the issues were resolved. After that, we dell the pluing and try to design the site with purely Elementor.

Now All the 404 issues are resolved. some were left we declare with 410 gone. that is it.
