You have poor air movement through your turf which is encouraging the

I wouldn't start again because you will effectively ruin any soil
structure you may already have.
When the ground is dry, push a garden fork deep into the surface to
'open it up' a little. This should be done as many times as is possible
over the entire lawn area.
Then, give the moss a good raking over to remove as much thatch as
possible exposing some soil, overseed with a good quality dwarf
ryegrass based seeds mixture, roll well, then finally feed at least 2-3
times a year.
Do not use moss killer on new grass seedlings, it will burn them up.
Given that you have very sandy soil which is prone to fertility losses
I would mulch all your clippings back onto the ground to recycle as
many nutrients as possible. This will also encourage worm activity and
keep your soil 'open' to some extent.

I'd go with rototilling the whole thing and starting over. If there
are weeds, you can apply Roundup/glyphosate when they are actively
growing. Before tilling, spread a few inchs of humus, which could be
composted leaves, well seasoned manure, or similar organic matter that
is available in your area. That will give you a much improved soil,
which will save years of frustration.

Test and adjust the PH as needed. Then re-seed using a high quality
seed that is suited for the environment. Apply starter fertilizer and
keep constantly moist for several weeks, then gradually back off the
watering.

Other choice instead of re-seeding is sod, but of course more $$$
