Error in Microsoft Sharepoint Server

I have a form where I can select from drop-down lists, people pickers, and attachment fields. It also contains checkboxes. Every click while using this form gives me a critical error message that asks if I’d want to “Start Over” or “Close” it.

Does anyone have a simple solution so that I don’t have to contact administrators or support teams?
