Hi community. I need urgent help. I need suggestions

I have Creta. My friend had asked for it and I gave. He was not picking phone on the day ge had to return. So I opened Bluelink app and pressed on force stop engine. 15 minutes after that my friend called that while he was driving the car took a 360 degree turn, stopped, was taking self but didn't move ahead, also because of that 360 degree turn I fell into the farm beside it. He got saved. Cars body is also perfect. My firend also is perfect. But the engine shut down and the car had to be towed. Since he tried to drive after shut down, the engine ran dry and timing chain broke. Now he tried to understand that how this accident happened. So he thinks may be a big Stone came and car suddenly turned 360 degree. This car has travelled to high altitude hill stations and nothing happened ever. How it can be hurt by a stone? I have not told anyone what I did with the Bluelink app. Can someone help me to understand that it's because of me this has happened?
