After updating my Xcode to the latest, I am unable to download an installed app container from the Xcode Devices screen. This currently works with older versions of Xcode with the same app on the same iPad. This worked with older versions of Xcode on the same MacBook as well (including the Xcode 26 beta before updating to the official release yesterday)

Same for me. It worked once after deleting and reinstalling the app I was developing, but then continued to show the error for every build or install after.

Xcode 16.4 works as expected.

Same for me. It is still reproducible on latest Xcode version. The last version where this error was not observed was Xcode 26.0 beta 2.

Same here, I cannot download the container. I thought my app was broken then I realized the xcode version change caused it.
