I would check for rubbing, but it could also be that the camber is off.

Not camber, more then likely its a toe out condition.

Agreed. Toe is out. A good alignment will help a lot.

What size wheels/tires - offset?
It could be toe/alignment, could be worn suspension components, it could be rubbing, could be both. Start with the easy part and visually look & check for physical signs of rubbing. This may or may not be correctable with an alignment OR wheel spacers / better offset. (blah blah blah blah...)
Check for rubbing in the photo areas. You can turn the wheel fully inward and compress it, use safety stands and be careful, get under and take a look OR take it to a shop and have them check.

I'm assuming you have a stock car with a stock suspension and setup. If you have anything other than stock, let us know.
It's not normal for tires to wear like that. The condition is serious in that, with the cords showing, the tire is at risk of failure. I would not drive on those tires any more than necessary.
While the alignment readings were "green", many are on the outer edge of what is acceptable. A good shop with a working machine should be able to dial the alignment in to where the readings are centered or very close to that in each of their specifications.
I'd start by getting the existing tires replaced. Tires worn as much as yours can affect alignment readings. You have to buy two. Given the mileage of all the tires, it might be worthwhile to replace all four.
After getting the tires replaced, get an under body inspection and an alignment. A simple, physical, mechanical check would take only a few minutes. Front and rear suspensions. Odds are, there is not a mechanical failure causing the issue, but just a bad alignment.
Unless you have a unique setup or track the car, the factory alignment specifications are fine. In most shops, their machines have a catalog of cars they select from, with the factory settings pre-installed.
After the tires and the alignment, I'd review the tires and treads at regular intervals. At least once a month, check pressures with a manual gauge, then look at the face of the tire tread. For the rest of the month, you could use the TPMS screen to confirm pressures are stable. Two to three times a year, I measure my tread depth with a gauge, to confirm things are wearing well.
I've been using the following gauges for a few years now. They work great.

Is that alignment sheet what it was at when it went in or after an alignment? If that is after an alignment it is irrelevant to how your tires wore before the alignment was done.

Welcome to owning a Mustang. Had the exact same condition with proper alignment on my 2018 GT, and I am expecting it at some point on the Mach.

Thatās really odd. Iām on my 2nd S550 as well and have not had that problem on either one of mine.

Hmm... I should add that I was running GT350 wheels and tires on my GT. Maybe that wheel width had something to do with it.

Possibly, if they were rubbing something in the fender well. The 350ās have wider fenders that accommodate the wider wheel & tire combo.
Thatās what looks like might be happening to the OPās tires as well. More aggressive toe settings will do it too, but by all accounts he has a pretty good toe setting. Nothing that would wear like that anyway

It's definitely serious if the cords are exposed. As to the cause ...
Check the local body shops for a frame alignment machine and have the chassis checked. It's possible that there's something out of whack with the chassis itself. I had this check done on my car before I purchased it. It costs a few bucks but in your case it might be worth it.
After that you'll have to have a serious discussion with your local alignment technician. Something is VERY wrong if the alignment is within spec but the tires are wearing anywhere. Inside, outside, center, whatever. I'd be concerned about driving it if it's wearing this badly on the inner edge of the tires.

Ball joint or something has gone bad. If that is the alignment after, then you still need new tires. Did they tell you what was off?
If that is the alignment before, well an alignment can be like a broken clock, right twice a day. If they do a poor job setting everything up, then you will get poor results that might be "right". Before/after would be helpful. Either way, get a new tire.
