  • Maybe run SharePoint Designer as administrator ? Nov 4, 2014 at 13:28
  • Does your list has duplicate columns names? Nov 4, 2014 at 13:31

Per your comment you have deleted a column.

Try to close the designer and open it again so it will refresh the new column layouts.

  • I tried this already. I closed the designer and opened it again. But it doesn't solve.

  • I created a new custom list. It has title columns only. Then I tried to create new form. But I got same error again. @ArsalanAdamKhatri

  • It seems your Item content type is corrupted. Have you modified the Item content type by any chance? Can you clear the site recycle bin and reload SPD? Nov 4, 2014 at 13:50
