I'll say this again: Your other tire has something stuck to the inside causing a flat.
If this were my bike I'd do two things. First, I'd put a new rim strip on/wrap a strip of tape around the rim to cover all of the nipples. Then I'd change tires. That almost 100% guarantees no flats if you install the tire/tube correctly.
