It is because apparently there’s a bug in iOS 17.5 that causes that, once you’ve downloaded a third part App Store (thus, only affecting EU), and you delete it, you can no longer download it.
No biggie, by the time anybody can find those out of App Store to actually download, we will be well into iOS 18 cycle. 😋
However, all this DMA chat belongs to a different thread altogether. 🖐️
