SQL Server error - when user tries to run a dialog

Our users recently started receiving a very generic SQL Server error when trying to use dialogs in CRM. 

As an admin, I am still able to run the dialogs just fine. The dialogs have all worked for many years in the past. Has anyone come across this or have a solution?
