I've been using the following YAML file in GitHub Actions to build my .NET MAUI app and upload it to TestFlight for quite some time without any issues.

I just updated it slightly to use .NET 9 as opposed to .NET 8 and now it's failing in the step that is supposed to download Apple Provisioning Profile with the following error:

Error: error:1E08010C:DECODER routines::unsupported

I think it's related to XCode but haven't figured it out yet. Any idea what maybe causing this and how to fix it?

Here's the YAML file:
