The failure rate of wide-body (ZO6 & GS) OEM wheels is a well-known topic on this forum. Rather than belabor the point I will just say that an investment in quality, monoblock forged aftermarket wheels would be a wise choice. As to which ones to choose - - there are many manufacturers who advertise on this forum. Search for "forged wheels" and happy reading.
Any quality, fully-forged aftermarket wheel in the correct size will do the trick. As you and far too many others have discovered, the OEM GM are junk. An "Advanced search" here for wheel problems will disclose about a gazillion relevant thread since the C7 wide-bodies debuted. All the best, in any event.
If you have the chrome ones. I have my old set that i replaced. 1 rear is cracked. but it will give you some spares. $500 plus shipping if you are not in central Texas.
but I recommend buying some forged wheels.
OP - Your best bet, if you plan to keep your GS, is to invest in a set of forged wheels. There are several businesses on the Forum that sell forged wheels. Price will vary from a couple $1K to several $1K. After meeting one of the owners and touring the Forgeline facility in Dayton, OH, I selected the wheels in the below pic. I am very satisfied with the wheels and the buying experience with Forgeline. Good luck.
After driving across country on old Route 66 in 2021 and having no problem with my original chrome wheels (18,000 miles), I replaced them with VX1R Forgelines just for a bit of insurance. Not cheap but a beautiful and functional addition to my 2019 Grand Sport.

There are a lot of wheel vendors on the forum and each offer many different designs to choose from. Check out their threads and see which wheel design catches your eye.
I really like the look of these, but the Forgeline F01 is “flow-forged”, not forged, correct? Flow-forged rims seem to run around $2k or more, vs +$4k for actual forged rims. Have you been satisfied with these? I’d like to replace the OEM wheels on my 2018 GS, which haven’t failed yet, but seem risky from what I read. Naturally, I’d like to spend less, especially for a design like this, but I want to be sure that I get rims I can trust.
Had a crack 5 years ago and put on a replica from Factory Reproductions with the idea that if that cracked I would go forged. It is still good.
The cracks are hard to predict. I never knew what caused mine but I have also had some hard, unavoidable hits which I thought certainly cracked a wheel but did not.
Aerolarri is getting a lot of good reviews for their forged wheels.

Thanks for the tip re Aerolarri. They do seem to offer prices that are almost “too good to be true”, but their website is a bit confusing, and although they claim to make fitment easy, among all the standard sizes they offer for C7 wide-body rims, the one size they don’t offer is the OEM 19x10 20x12 setup. I think I’ll investigate further before opting to go with them.
Literally any aftermarket wheel will be better than the GM OEM crap wheels.
Yup
Even cheaper cast wheels are superior to the GM Humpty Dumpty wheels. You can repair the original GM wheels, but all the Kings horses and all the king's men cant put them back together in a way that they won't crack.
I went trough at least 8 wheels on my 19 GS between being bent, cracked or both. My Wife refused to ride in the car any more with the **** OEM wheels. I didn't have a ton of money to spend on wheels so I looked around and bought new wheels from E5wheels. They are spin forged and were under 3K for the wheels. Dante at E5wheels was great and I had the new wheels in a few days. Top pic with OEM and bottom with the new. I met them a Carlisle last week and they were very nice.
