I just tried again, and it works for me …

Did you type it in, or copied it? There is a single space before the 2nd question mark, to remove an optional space between the comma and the following text. Without the space .. oh okay, without the space it also works :-)

If you cannot get it to work, eliminate by removing entire bracketed groups from the right: first, see if

^(?=[^t]{22,})([^,]+,) ?

finds anything at all, and if not remove the second group and test.
