I’m here, but confuddled 😀
As you say, it’s most unusual for tension to be out as much as that, and the size of a swatch should increase with the size of the needle.
22 rows giving 2 inches of knitting using Aran weight yarn? Are you sure, OP?
All I can suggest is that if all else fails have you someone who would knit the swatch from scratch for you? If so you could give her the yarn and recommended needles and see what happens- that way if you are doing something you don’t realise you’re doing it will come out in the wash.
