Any lead would be appreciated.

There is currently a known issue that you get exactly this kind of exception when you try to calculate a model that has no elementary flows: https://github.com/GreenDelta/olca-app/issues/13. Maybe this is the same reason here?

I think your model is probably not well formulated; validate the database and you will then see issues; does this happen with every product system or only with some? What kind of database are you using? Did you import the database from somewhere else? Thank you.
