i'm 44 and i feel this deeply.
i'm a reasonably handsome guy--average, i think, but i take pretty good care of myself, and i've been drinking milk--and on paper i think i'm a pretty desirable partner. (my go-to joke is that unfortunately, women don't date guys on paper, unless they have a stationery fetish, and that's not really my thing.)
however, on dating apps, i do awful. awful awful. even just on mainstream/traditional apps, very few matches. don't even get me started on what a waste of time feeld has been. i haven't done okcupid in awhile, last time i tried it, it was spam central, but maybe i'll try it again.
when i go to lifestyle events locally, i get a really strong sense that this is a young person's game and it's really not for me. i'm the first to admit that i'm somewhat pessimistic, but i'm pessimistic because i'm following the evidence. i just haven't done well, and i don't know if that's because of something about me in particular or because of some demographic i fall into.
regardless, it's tough out here, but i think maybe it is for all of us, in some way or another. i don't think being older rules anything out for you. perhaps it won't be as easy as for someone in their 20s, but especially depending on your locality, etc, i think doors are still open.
