I get this error from Process Builder at times. It happens when we have a large batch of records being inserted. "An Apex error occurred: System.ListException: Duplicate id in list: "
I am trying to assign a Contact from a Process Builder on a custom object that has a Lookup to the Contact. Could that be why?

Is is possible multiple of the custom object look up to the same contact? If so, that might be the problem.

If that's the case, I think I can fix it. Would you be wiling to test the fixed package, in a sandbox/scratch org?
