A friend had an issue recently but while it was odd, I think one has to be careful with the tubeless ENVEs. His was the AR version and tubeless. I don't think he used the ENVE tape but some other tape. Anyway, while the shop was inflating it to seat the new tires, air escaped into the lower chamber (that is not meant to be pressurized) and it blew up that part of the rim. ENVE warrantied it, which was great. ENVE later said to only use their tape and valves.
I recently warrantied one that did the same. The issue is more their valves or rather their retaining nut for the valve. They drill it to allow any air that leaks into the lower chamber of the rim to escape. I have never had or seen this issue with any other rim when using it tubeless. Including the ones we use.
In other words if the lower rim chamber gets pressurized it will blow completely off the rim in the most catastrophic and exciting way.
