Engin will not start in 200 miles

I got this on my 2020 1500 ecodiesel. I was on my way home from a trip to Calf. about 250 miles away from my dealership. I drove right to the dealership told them what the problem was and they drove in the back and told me they would call and let me know what the problem was. Two days later I get a call that they could not start the truck or do the Diagnostics because the CPU was fried and had to be replaced to go any farther. Is it normal for this to happen?
