Transmission issue, I’d get it towed and I would look up Nissan’s transmission warranties as they extended it to something but I’m not sure on your model and year, it idles fine and revs fine so that means your engine should be good, it only stalls when put into gear and obviously only factor being added is the transmission so that’d be my first guess, and might be the torque converter or possibly internal as it is a CVT and Nissan.
