New beta product editor doesn’t work with WooCommerce Product Vendors

Hi @notamax

In the current beta stage, the new product editor doesn’t support extensions that depend on product listings, such as WooCommerce Subscriptions or product vendors. You can find more details here: https://woocommerce.com/document/new-product-editor-beta/#section-18

I hope this helps! If you have any other questions, feel free to ask.
