Help me understand what cooked my ESC

This DRV fault came out of nowhere and my stormcore is beat. There’s no obvious visible damage and it was in my board the whole time. I had over 3500mi on this thing without a single issue. I did a quick search but after reading a few topics, im still not any closer to understanding what happened. Does anyone have insight for what ive got going on here?
Thank you!

The drv chip died from a voltage spike.
Were you braking when it happened?
Are you on 12s?
You can buy a new one and replace it but it is a difficult procedure.

No i was cruisin at a moderate pace on flat

Same thing happened to my 100D. Was just coasting downhill and it shut off. Super weird. The previous day I was riding on some bumpy dirt roads, so maybe that was related but I doubt it.
