Front left tire stopped rotating

A couple days ago in Minnesota my rwd 300c got stuck twice in 2 different snow drifts during a blizzard with wind gusts of 50 MPH+, temperatures in the negative single digits (rain right before the blizzard, frozen ice underneath). The second one I got out of was about 6-9 inches. The car was driving fine through the unplowed roads afterwards, didn't hear any abnormal noises coming from the car/wheels. I got to a gas station and was stationary for about 15-20 minutes with the wind gusts and piercing snow hitting the left side of the car. Once I put it in drive and started moving forward I didn't notice anything til I started to turn left out of the pump area and got stuck in 5 inches of snow immediately. My friend helped me move it backwards and noticed that the left front tire wasn't rotating. I also noticed when I put in drive and try to move forward the car has a cracking/popping sound like something is frozen trying to break free. When I turn the wheels completely to one side and look into the wheel well, there is solid ice built up around the strut shock assembly, where the sway bar end link meets the sway bar, around/inside the knuckle of the tension strut that's near the engine cradle. I sprayed most of the ice with a can of deicerr in hopes to break free the ice and make the tire rotate but with no luck. So my question is, why would my tire just stop rotating? Is it possible that my wheel bearings are frozen or would all the other ice build up cause it to not rotate?
