(I'm not sure if this'll help you...)
I had the same issue with an app our company has in the App Store.
The reason was because we have both a Developer Program (so we're allowed to submit an App onto the App Store) and an Enterprise Program (so I can make in-house copies of the app).
Our Bundle ID was registered under the Developer Program, but I had logged into the Apple Developer website and had chosen the Enterprise Program group.
In the Apple Developers website, the Identifies\App IDs didn't show our Bundle ID, because it was actually registered under our Developer Program... but, of course, it still refused to let me create the Bundle ID a second time, and, as usual, the error message gave no clue as to what the problem was.
I really hate the whole Certificates/Provisioning Profile stuff with Apple. Their error handling/reporting, when you get something wrong, is a farce. And it'll happily let you create non-working apps, deploy them to a device, then report a "Your app could not be installed at this time" when things go wrong.
Even yesterday, when I was ready to deploy a new version of the App to the App Store, I could create an Archive, the Validate said it was all fine, but then when I submitted it, it reported 3 errors in my .plist file.
Oh, and remember that your Bundle ID is stored in the .plist file and in the settings:
Make sure this Bundle ID is correct in both places!
(Sigh.)
