Error while installing windows service in Amazon EC2 Windows Instance

Hi AWS, I am trying to deploy a windows service using CI/CD pipeline with the help of GitHub Actions. The Windows service is written in .NET Framework 4.7 with C#.

Here is the code repo: https://github.com/arjungoel/WindowsServiceDemo

Pipeline Code:

name: "Deploying a CI/CD for Windows Service using GitHub Actions"

on:
  workflow_dispatch:
  push:
    branches: [ "master" ]
  pull_request:
    branches: [ "master" ]

jobs:
  build:

         runs-on: windows-latest
         defaults:
           run:
             shell: cmd

         steps:
         - name: Checkout code repository
           uses: actions/checkout@v3
      
         - name: Setup MSBuild

         - name: Setup NuGet
           uses: NuGet/setup-nuget@v1.0.5

         - name: Restore Packages
           run: nuget restore WindowsServiceDemo.sln

         - name: Build solution
           run: msbuild WindowsServiceDemo.sln /p:Configuration=Release /p:DeployOnBuild=true

  #    # - name: Display the service status
     #   shell: powershell
     #   run: Start-Process powershell Get-Service -Verb RunAs

The build job is running on GitHub Hosted Runner and the deploy job is running on Self-Hosted runner which is configured on Amazon EC2 Windows instance. Now the problem is at the installation step I am getting this error:

Exception occurred while initializing the installation: System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\actions-runner\work\WindowsServiceDemo.exe' or one of its dependencies. The system cannot find the file specified.. Error: Process completed with exit code -1.

and I believe this is a general permission issue in windows but I am not aware of how to fix it. Is there something which I have to enable in the OS settings manually or any small change in the code can help me get rid off this issue. I have tried to find a post on Stack Overflow or YouTube but nothing helped and I have already spent more than 15 hours to get rid off this issue but no luck yet!

This issue is an extension to the issue already opened i.e. https://repost.aws/questions/QUmNS6bap2TIOiy_Ca6XpDog/windows-service-is-not-found-in-t2-micro-ec2-windows-instance

The instance size is not an issue as I have tried it with a larger instance size like t2.large.

Please help as I need to fix this ASAP!
