Unsupported Architectures during upload to store

Hi

Context:
I have an app for ios and android developed with dotnet maui.
Normally during summer time the development stops and I pickup the development during the winter.
I am doing the development and builds on a M2 MacMini in VSCode.
I updated my Mac to 27 (GoldenGate). Running XCode 26.6 (and XCode 27). And the latest dotnet sdk and workload for maui.

I updated my project with the latest packages, did a minor code update and tried to use Transporter to upload to the Store for TestFlight.

The upload fails because it detects a unsupported architecture (x86_64) coming from the libskiasharp.framework in the IPA.

lipo indeed states that the ipa zip contains that architecture.

What is going wrong here, why is this now happening.

I am chasing my tail here.

Thanks
