AppConnect on Xcode Cloud workflow creation that repo can't be found or does not have admin rights, but neither are true

I'm setting up a first workflow in Xcode Cloud and when I go through the flow and reach the 'Grant Access to your source code' pane, my projects repo is listed as primary and has a green checkmark next to it, but one of my SPM dependencies does not. When I press the 'Grant Access' it launches AppStoreConnect which complains the repo can't be found or I don't have the correct admin permissions.

I'm using BitBucket Cloud and both repos are mine and I am the admin for both. Xcode itself will build the dependency locally correctly.

I did see that the dependent SPM package needs a Package.resolved checked in, which I've now done, but I can still no longer get past the Grant Access step.

When I try to add myself as admin to the dependent repo, BitBucket says I can't be added because I'm already an admin. This is the same for the projects primary repo as well. But Xcode still thinks I only have read access. How do I get passed this? Xcode isn't even telling me what repo is troublesome:
