Deletrical Message?

Hi! I have a 2020 Civic. Haven't had any problems with it. I've kept up with all maintenance. I had a baby and wasn't able to drive it for 3 weeks (husband drove it a bit but then we were getting some break ins so just kept it in the garage for almost 3 weeks). Turned it on today and it says there's an electrical error and the brake was locked. Any advice?
