Error with Pods Item List

So i’m using Pods Item List in one of my pages and for some time it was working fine but recently i tried to edit one of my item list but the box displays: “Block found an error and can’t be viewed”. I had lots of codes inside the “Content After List” box. So my question is, how can i access these codes inside content after list box without clicking to edit the item pod since it displays an error?

If my question is confusing please tell me and i’ll give more details.
