Please deactivate all the third-party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then, activate the third-party plugins one by one and check which plugin is creating the issue for you.
Otherwise, if the issue still exists, then keep the third-party plugins deactivated and let me know I will check and give you a possible solution.
This issue occurs because the single product layout is missing elements that display the product description. As a result, when you try to edit the product using Elementor, an error appears.
To resolve this, you need to add either the Product Content element or the Product Tabs element with the Enable Description Tab option enabled.
