With such low mileage I find it hard to believe your ECM failed unless you've been storing it outside under a tarp all winter or a place with very high humidity OR your car was a flood damaged salvage car.
I always keep my car hooked up to a battery maintainer when not used for longer than a week. Today's car electronics require a fully charged battery at all times.

Car is stored in a clean heated garage, low humidity for CNY in the winter, was def not a flood/salvaged car, and no signs of rodents or anything. The day before, I even started it up and pulled it out to turn it around and it was fine- then boom, all sorts of issues.
Being an HVAC technician myself, I have to deal with loads of control boards, miles of wiring, various sensors, harnesses etc, and have had multiple situations where I have had to replace control boards without a direct reason of why the board failed - Do I like that? nope, not at all. I def want to know what happened so it doesn't happen again, but sometimes it is what it is.
