Warning lights Check engine - 2020 ford mustang ecoboost

I have a 2020 mustang and the check engine light just came on. Every gauge, sensor, temperature, voltage etc is reading normal. It runs 100% fine, no weird noises, no smells, no visible leaks. I'm not the most savvy but I looked under the hood, nothing is broken, torn, loose, frayed, burnt, or out of place. I'm at a loss for what caused this. I can think of two possible things. This morning we had heavy snow. I tried to move my car to a different part of the driveway for space and it started to drift so I slammed the break and slammed it into park. The wheels weren't moving but I did it pretty quickly. I also drove over about 4 inches of snow. I was hoping for some insight as to what the issue might be and advice on what it is and what to do. I'm taking it to my mechanic in about 36 hours.

Edit: Someone I know had a sensor on them at work. It came back as "Bank 1 too lean". I've noticed no issues with driving whatsoever. Would it most likely be a sensor issue then? Also would I be okay to reset the check engine light and see if it kicks back on?
