We have a SharePoint list with thousands of entries. The list has Nintex forms. When I go to edit a list item or even view it, the "Working on it" screen never goes away and the form is never brought up. Is there a way to troubleshoot specific form entries or is this more of a SharePoint list thing?

Could it be that the list items (there are 2 out of over 6k) are simply too large with all of the information/attachments?
I am not a SharePoint admin/developer and have just been thrust into learning Nintex from scratch, so go easy on me. Any assistance would be appreciated
