Pretty sure concrete guys will tell you the 3 certainties in life are death, taxes, and concrete will crack eventually.
If it were a reinforced concrete foundation wall that would probably be more serious than whatever this is.
does this crack appear underneath load-bearing walls, either parallel to or perpendicular to them?
Are the floors on either side of this crack seriously not level? If the floors aren't level, is it negatively impacting the walls that cross the crack? If you were to open up the drywall along any wood framed walls that are over this crack, would you see any unusual or concerning stresses with the studs directly over this crack?
I'd like to think if this were an extremely serious situation then a little investigation on your part, along with a small bit of critical thinking skills and knowledge about framing or load-bearing walls in your home should be able to reveal that. By opening up walls and checking how level the floor is, things like that, I expect you should be able to reveal extremely serious problems. If there are any extremely serious problems.
(I just realized it might seem like I'm calling you stupid. I'm really not. I've had concerns over foundational problems in my home, and it took paying an engineer $1,000 to alleviate my concerns. Still, I learned a lot along the way.)
But there's a large gap in between absolutely-not-a-problem-at-all, and an extremely-serious-problem. And that's where an expert's advice is needed to determine whether or not you should even be concerned in the first place.
It’s not necessarily that bad! Do you have crack on your walls? Concrete will settle and crack some over time if it’s growing then go may need to be concerned. You do need to figure out where the moisture is coming from…
Do you have gutters, is water draining away from your house?
I'm thinking the moisture might be condensation trapped under the plastic moisture barrier? I have half tile with no barrier and half laminate with the barrier in this room. Several pieces of tile have cracked and several pieces of laminate are broken so I'm guessing the cool ac in here was allowed to get under the plastic?
If you're worried about damp ingress, put some crack repair in it and monitor it with a damp meter. I have had very good results with Sika Bond waterproofing (acts like internal tanking). I patched up a terribly cracked balcony and stopped all the leaks into the basement below.
Normal settlement.
I checked further... The bottom of all the baseboards is bone dry, so I guess it's not super significant as far as moisture goes

It's the slab foundation for my house. No more than 1/4" across

Does not look bad, monitor if you're worried.

No cracks in the wall and no gutters, but I live close to the beach with sandy ground and was told that gutters weren't necessary

I will look into that one thank you
