How to fix a cracks in the polymeric sand joint in patio

I laid patio earlier this year and after a few months, it seems like the ground on one side sunk a bit, with a result that the polymeric sand joint between paving stones got small cracks here and there.

I doubt the ground will sink further, but before winter comes I would like to fix this so water doesn't get in the cracks and freeze, potentially causing further damage.

How should I do this and what should I use to do this?

Make sure it is fine sand.

Are those a surfaced clay or concrete pavers or are they real interlocking concrete pavers?

Are they laid over concrete somehow or are they laid over a sand setting bed and compacted base?

Polymeric sand is a little "gimmicky" and in 40 years, I have never seen it used in a real paving job that required strength.
