Could be anything from a simple sensor failure due to low voltage from not driving it enough in the winter or you may have overheated the diff and damaged something while you were trying to get it up your driveway. You won't know till you take it in and get the fault code read and the car inspected. My advice would be to get it sorted ASAP as new parts sometimes take weeks to deliver from overseas.

Why assume there is anything wrong here just because it says "error". The error message happens to be perfectly normal under described conditions with summer tires. You just have to have minimal understanding of how these systems work and what happened. The differential was working hard as would be expected when buried in snow. That is why you will get this message every time when "rocking" the car out of snow in a manual. Don't assume error means something wrong. My car gives the same message if I get stuck in snow and do some back and forth to try to get it out. There was no need to get dealer involved.
