Error Message with the Create List

Hello,

I was updating a create list “WP block. Adding items, deleting items, updating this list and now when I try and add a new item, it goes to an error message and won’t let me continue to work on that create list. This particular create list is live on my website and looks fine from the front end. The error message I’m getting is “This Block has encountered an error and cannot be previewed”, when I try and add an item to the list.
