I am getting this issue also and I am on RC Xcode and RC macOS Tahoe. I took the .icon file out the 'App Icon' section of the Target settings and it allowed be to archive properly. Wondering if the Connect server is running into a bug with the .icon files. Hoping it gets fixed soon and I can hopfully push a 'day-one' update alongside the release of iOS26

I am also still having this issue (ios17b3 and xc15b4). I don't have anything in my 'VPN & Device Management' tab except for VPN. The popup on my phone says a network connection is required to verify - I have tried cellular and wifi with no luck. The popup on Xcode says the same thing about needing to be verified and to find it in that tab in settings. Deleted the app from the phone and started again, re-signed into Xcode signing, and did everything I think I could do, and no luck. I hope there's some fix out there so I can start testing projects on a physical device again. Thank you in advance!
