I've run f3probe on a troublesome SD, it says : DamagedThat sounds a lot like a counterfeit SD card, although you'd need to do a bit of testing to be sure of it. One style of counterfeit is to put a fake size on a smaller card, programming the card with false size information. It will seem to work at first, until you write beyond the real size of the card. The imager will write a new OS image at the start of the card, so will work if the real card size is sufficient for the OS, but the running OS will write more randomly across the entire allocated space.
You can test the card from a working Pi (or other Linux system) by sticking it into a USB card adapter, and using the "f3" package to test it.

On a SD right out of the box, it's legitimate.
8GB version.How much memory have your Pi4’s got?
Are they using official power supplies?
And no, I'm using a POE module (not official).
But for both, as I said, I've installed over 300+ pi with the exact same hardware setup, without any issue, with some running perfect 24/7 over 2 years now. The only change is the OS image.
I could've landed on a bad SD batch, but the way that they all fail in the exact same manner at the exact same time, makes me doubt about it.
