2015 570 over voltage code now won’t start

I have a 2015 570 with about 1300 miles on it. Went to ride it up the street today and when I pulled out of the garage the check engine light came on and it stalled. Looked up the code and it was an over voltage code. Started it back up and rode it a short distance hoping it would clear itself up but it didn’t. Pulled back in the garage, shut it off and restarted it again in neutral and it was idling at 2300rpms. Disconnected the stator so that it would just run off the battery, and the problem was still there. Disconnected the battery and went to work, got home, reconnected it and now it just turns over but won’t start.

I have a voltage regulator on order but don’t know what could be causing the no start issue. The check engine light is no longer on.

I appreciate any help, I’m kind of stumped and don’t want to have to bring it to the dealer.
