In my case - The URL Sits on Load balancer shared with 5 different WFE servers. Issue got resolved after pointing the host file to one of the WFE's server. No Now form is opening normally with all the field controls without any error rendering controls in SharePoint designer. As a workaround I did pointing to individual servers to see if any one of server is culprit and causing issue? every individual server works fine then concluded that issue could be due to load balancer. Because here we are bypassing load balancer pointing to host entries. Though it is not a permanent fix, for time being we need to do host entry on local machine inorder to edit and make changes to form.

The controls you have are custom controls. Hence, you aren't getting the general preview for SPD. SPD will not give you data in What-You-See-Is-What-You-Get mode. It can only decode SharePoint specific elements (and not custom elements/controls)

Are the fields on form - out of box or custom fields?
