Project Settings file not found CI/CD Github

I am trying to update my unity project to include CI/CD on github. I have followed all the steps and put the appropriate projectPath. However I still get an error. I am using Unity version 2021.3.2f1 is it just unsupported? What can i do to use CI/CD?

name: Build project
    
    on: [push]
    
    jobs:
      buildForAllSupportedPlatforms:
        name: Build for ${{ matrix.targetPlatform }}
        runs-on: ubuntu-latest
        strategy:
          fail-fast: false
          matrix:
            targetPlatform:
              - StandaloneWindows64 # Build a Windows 64-bit standalone.
            projectPath:
              - MyProjectName
        steps:
          - uses: actions/checkout@v2
            with:
              fetch-depth: 0
              lfs: true
          - uses: actions/cache@v2
            with:
              path: Library
              key: Library-${{ matrix.targetPlatform }}
              restore-keys: Library-
          - uses: game-ci/unity-builder@v2
            env:
              UNITY_LICENSE: ${{ secrets.UNITY_LICENSE }}
            with:
              targetPlatform: ${{ matrix.targetPlatform }}
          - uses: actions/upload-artifact@v2
            with:
              name: Build-${{ matrix.targetPlatform }}
              path: build/${{ matrix.targetPlatform }}

The error I get is:Project settings file not found at “ProjectSettings/ProjectVersion.txt”. Have you correctly set the projectPath?

Below is my ProjectSettings/ProjectVersion.txt file

m_EditorVersion: 2021.3.2f1
m_EditorVersionWithRevision: 2021.3.2f1 (d6360bedb9a0)
