Variable Products & Gravity Form not working together

Hi. I have a variable product as I offer 2 different gift box options with my gift boxes.
On all my gift boxes I have a gravity form as I need to collect info, hand written card note, personalised name etc.

When I have both set up and fill in all the required info it does not allow me to add to cart and says please select a product.

Can anyone help with this please

We have the same problem with our woocommerce site. We finally figured that removing a popup which had a GF in it solved our problem. We are using Elementor.
