I got the same issue when I followed your process of creating an Azure web app and connecting it to the GitHub repository by selecting the CI-enabled option.

The dotnet publish command is failing because of the output directory path is not valid. So, I changed the dotnet publish and upload-artifact path in GitHub yml file as shown below.

- name: dotnet publish
  run: dotnet publish -c Release -o ./myapp

- name: Upload artifact for deployment job
  uses: actions/upload-artifact@v4
  with:
    name: .net-app
    path: ./myapp

Below is my complete workflow file.

GitHub/Workflow file:

      - master

          slot-name: 'Production'
          package: .

After changing workflow file it is successfully deployed to Azure App service.
