buildx failed with: ERROR: failed to solve: failed to push ghcr.io

Given a public repository ( you can find a minimal reproduction repository here https://github.com/matthiashermsen/deleteme ) with a Dockerfile with this content

FROM alpine

and a Github Actions workflow with this content

name: Release

on:
  push:
    branches:
      - 'main'

jobs:
  release:
    name: Release
    runs-on: ubuntu-latest
    permissions:
        contents: write
        packages: write

    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Set up QEMU
        uses: docker/setup-qemu-action@v3

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3

      - name: Login to GitHub container registry
        uses: docker/#-action@v3
        with:
          registry: ghcr.io
          username: github-actions
          password: ${{ secrets.GITHUB_TOKEN }}

      - name: Build and push Docker image
        uses: docker/build-push-action@v5
        env:
          DOCKER_REPOSITORY: ghcr.io/${{ github.repository }}
        with:
          platforms: linux/amd64,linux/arm64
          push: true
          tags: ${{ env.DOCKER_REPOSITORY }}:${{github.run_id}}

I would expect the workflow to be fine but unfortunately the last step fails with the error message

ERROR: failed to solve: failed to push
ghcr.io/matthiashermsen/deleteme:latest: unexpected status from POST
request to https://ghcr.io/v2/matthiashermsen/deleteme/blobs/uploads/:

You can find the error here https://github.com/matthiashermsen/deleteme/actions/runs/9312939002/job/25634525513#step:6:166

Is something wrong or am I missing something?
