Github Actions: Multiple jobs single release

Question

I am having 2 jobs in the Github runner. The first job builds the android apk. The second one to build a zip file. I want to have both the apk and the zip file in the same release. But after the apk is published into a release, the zip file does not get published into the release. The error shown is:
Validation Failed {"resource":"Release","code":"already_exists","field":"tag_name"}
buid.yml:

Any help is greatly appreciated!
Thank!

The error says that:

Release with this tag name already exists

It is coming from your last step:

ncipollo/release-action@v1

By default this action seems to be always trying to create a new release ("This action will create a GitHub release"), but according to its documentation here you can alter that behaviour by adding:

allowUpdates = "true"

- name: Create Github Release
  uses: ncipollo/release-action@v1
  with:
    artifacts: "build/windows/runner/Release/AppName-${{github.ref_name}}-windows.zip"
    replacesArtifacts: false
    token: ${{ secrets.TOKEN }}
    allowUpdates: true
