Hi there,
It could be SharePoint issue; perhaps an admin turned off sandboxing. Please make sure sandboxing is turned on.
Are you using Office 365? Or is this your SharePoint server? If it is a server you can access the logs on, trigger the error by trying to open the form and check the log files - default locations here.
Kind Regards,
