Unable to Create Products

Hello, I am having trouble when I attempt to create new products on my website using the WooCommerce plugin. When I click the “Create Product” button, I receive the following error message:

Warning: Creating default object from empty value in /home/telebarn/public_html/wp-admin/includes/post.php on line 708

I have already attempted disabling all other plugins and it did not resolve the issue. I have also already attempted to contact woocommerce but with no success. I would greatly appreciate any help that can be provided
