Anyone with the same problem?
Xcode 16.1 is not available in Xcode Cloud
We've verified that Xcode 16.1 is available on Xcode Cloud. If you're still experiencing this issue, can you please submit a feedback and provide the name of the workflow?
Saw the same here too. To clear it I had to drop down the version list and select the "Xcode 16.1 (16B40)" build again. If I had to guess, it has something to do with the "usage update" announcement - maybe there's a new "version" of that Xcode 16.1 release for Xcode Cloud.
¯_(ツ)_/¯
