Why can't I get self drilling anchors into the wall

Assuming you do have plasterboard/drywall, I've found a couple of tricks to make these plastic anchors go in more easily.

The first is to start with a metal one, then swap it to the plastic sort. That only works if the threads are the same pitch (spacing), but the ones I can get easily do match. This is probably the most helpful in your case

The second is to start the hole first, so that the tip doesn't have to work so hard and as soon as you start twisting the threads can bite. You can either use an awl, or lightly tap the fitting with a hammer (I use a metal fitting again). Either way, this breaks through the paper, any skim coat, and accumulated paint without chewing up the threads.

Note that stud finders can miss studs, and drywall can be fitted to thin battens which are harder to detect and often closer together. I have masonry walls with battens and plasterboard. If the fitting is going in by the thickness of plasterboard, then jamming, you're almost certainly hitting something. Using a metal fitting would give you certainty, at the expense of damaging the plasterboard if it does hit a stud or something else solid.

But fittings provided with products are often flimsy junk, so it may just be that they're too soft
