[BUG] MSIX doesnt built in Azure DevOps Task

Project
MSIX SDK with MAUI app.
Project location: https://dev.azure.com/saigkill/JobApplicationManager

Describe the bug
I'm using the MSIX build and package task. After the task, it will be marked as succeeded, but no MSIX package can be found.

To Reproduce

1. Clone the project
2. Set a build task with the parameters in the screenshot.
3. Run the pipeline.

Expected behavior
In general i'm expecting the produce of a MSIX package, or a failed status.

So i'm confused. On the one side the project is build correctly, and on the other side not. And i don't know, how i can fix it.

Start with the Azure DevOps project and the logged MSBuild command, especially the MSB4078 warnings for JobApplicationManager.csproj and JobApplicationManager.Tests.csproj. Confirm whether the task should produce an MSIX package or fail when the projects are unsupported; done means the task reports the correct outcome and the expected package is present when the build succeeds.
