Add Attributes not saving in Edit Product

Hello,

I have been trying to Add a Custom Product Attribute in the Attributes Tab for EDIT PRODUCT, and it is not saving.

This is a new issue.

I reached out to my Web Host, you rolled back to WP version 5.6. But it didn’t help.

I reached out to WooCommerce, and the used Storefront and deactivated all plugins, and I was able to save then.

WooCommerce support suggested I contact you.
