Have you done any Customization in your Child Theme? If yes then please remove that Customization code and check back and if no then please delete the Child Theme and then create it again and check back.
If you added those widgets/elements “Product Gallery and Tabs” with activated Parent Theme under Custom Product Builder then you have to check and add them again after activating the Child Theme, because the widgets messed up/removed sometimes when you switch the theme.
Otherwise, please share your site WP Admin URL and Credentials with me here, in the private content area of this topic, like below listed format, so that I’ll check it for you further on your site.
