Gutenberg editor – Product Grid Block template Editor not loading

I am having a problem with the WooCommerce Product Grid Block Editor when using a child theme for the Twenty Twenty-Three theme. The issue is that the template editor is not loading correctly, and instead of seeing the expected content, I only see grey boxes. The same issue is also in other product grid templates such as “Products by Attribute” and “Products by Category”. But all other templates such as the “Single Product” template are working fine.

Here’s a screenshot of what the template editor looks like:
