What could be the cause of the basement stairs separating from the drywall?

This is because the shrinking of lumber in use. Also if you did renovation in that are could cause that problem.. There are couple other things that can be considered.

Cost:-

Cost depends upon material in use amd number of steps.

Staircase not secured with framing properly. Amd weather causes could efect that too.

It's a stairs structural issue and we should put stringer on the both side.

Firstly. The stringers should never touch or be secured to the walls going into a basement. They should only be hung at the top and left to float. Otherwise. This could cause squeaks and additional pressure on the structural framing. A small space is good. We do not know the size of your gap therefore difficult to assess. I would suggest to cover it with a trim board like a door stop securing it to the stair stringer top not the wall. Leave a minimal paper thickness space away from the wall. Caulk with dapp. And paint.

The dapp should flex enough during use.

If your gapp continues to increase there could be structural problems which could become costly. But I believe you'll br good this this solution. For now anyway. Feel free to contact me if any further issues arise.
