I have a basement staircase "outdoors" where the steps are loose and have been for many years, but now I'm tired of walking on them and need to find a solution to secure them permanently. Currently, they are fastened with French screws and plugs. The walls are made of old hollow concrete blocks, so plugs and screws are not optimal. Does anyone have tips or ideas for a solution?
See pictures.
Under the steps, there is a sloping concrete incline. Maybe it's possible to find a solution that attaches to the slope?

I read about a tip regarding kitchen installation that sounded sensible. Drill the hole, fill it with anchor mass, press a suitable threaded rod into the mass. Attach the step with a nut on the rod. Unclear if it works in your case with installation on two wall sides.
I also think it's a good idea, and since you already have old holes for plugs, you can drill new ones in both the steps and the wall for the threaded rods, and then insert the rods and let them cure while the old screws hold the construction in place. Or, if you want to avoid drilling too much, attach one rod per side at a time and temporarily hold the step with only the front or rear pair. And remember not to step on it...
Perhaps a crazy idea, but say there's a hole directly inside and the rod disappears, in principle, you could use a long rod, and screw on nuts far along the rod, and then push it first deep into one side, and then push it into the other hole. Then tighten the nuts. Then it sits like a rock and supports itself with a through rod. All in one go, with anchor mass and all.
