I don’t know if there “is or isn’t a shidduch crisis”. Nor have I spent the time to think whether there is or isn’t a haskafik issue with the concept of a shidduch crisis.
What I do know is that there is a major compatibility problem. The older boys who are of dating age in the yeshiva world have significantly more exposure and gashmiyus then the girls who are supposedly looking to marry those guys. There are significantly more girls who just want a serious learning guy, then guys who want to marry the girls who only want yeshivish guys.
