This is just a guess based on trying to make it home with a slow leak before.
If you ride on a partially flat tire (or just very low pressure) the inner tube will start to get pulled out of position because of friction (picture it rotating in relation to the rest of the wheel). This makes the valve start leaning in the hole. Done long enough this would presumably make the valve snap.

Even your valves want you to run tubeless

I always end up drilling out the hole and using Schrader tires

This can happen if the tire isn’t run at a high enough pressure.
If the tire pressure is too low, the tire can slip on the rim and drag the tube along with it. When it does that, it can do exactly what you see in this photograph.

Just recently had this kind of failure, it was new for me too

Was the nut too tight against the rim, thus contributing to pulling the valve out?
Or not tight at all, thus allowing side-side flex that damaged it and allowed it to pull out?
I see that the bottom threads are pretty dirty, which makes me think the nut was completely loose and allowed the valve stem to wobble like crazy, eventually damaging the tube at the junction.
