Why does Visual Studio IDE not run on my Windows laptop.

Question

I can launch the app but it never gets passed the loading screen, it always just disappears after a while. I am running visual studio community.

Answer 1

If your app launches but never gets past the loading screen and eventually crashes, there could be multiple reasons for this behavior. Here are some steps you can take to diagnose and fix the issue:

Check Event Viewer

Open Event Viewer:

• Press Win + R, type eventvwr, and press Enter.
  • Navigate to Windows Logs > Application.
    • Look for any errors or warnings that occurred around the time the app was launched.
    Analyze the Error Messages:

    - Look for error messages related to your app or Visual Studio.
    
       - Note down the details of the error messages, especially the `Exception Code` and `Faulting Module`.
    

Enable Detailed Debugging

Set Breakpoints:

• Open your project in Visual Studio.
  • Set breakpoints in your code, especially at the start of your Main method and other critical initialization points.
  Step Through Code:

  - Run your app in Debug mode (`F5`).
  
     - Step through your code using `F10` (Step Over) or `F11` (Step Into) to identify where the app is failing.
  

Check Output and Diagnostic Tools

View Output Window:

• Go to View > Output in Visual Studio.
  • Select Show output from: to Debug.
    • Check for any messages or exceptions being logged.
    Use Diagnostic Tools:

    - Go to **Debug** > **Windows** > **Diagnostic Tools**.
    
       - Start your app and monitor the diagnostic tools for any performance issues, exceptions, or memory leaks.
    

Common Issues and Solutions

Initialization Errors:

• Ensure all dependencies and configurations are correctly set up.
  • Check for missing or incorrect settings in your app’s configuration files (e.g., appsettings.json, web.config, etc.).
  Missing Resources:

  - Verify that all required resources (e.g., images, data files) are included in your project and properly referenced.
  
  **Unhandled Exceptions**:
  
     - Wrap your initialization code in try-catch blocks to catch and log exceptions.
  
        - Example:
  
        ```
        csharpCopy code
        try
        ```
  
        **Dependency Issues**:
  
           - Ensure all required libraries and packages are installed and compatible with your project.
  
              - Use NuGet Package Manager to manage and update packages.
  

Reinstall or Repair Visual Studio

Repair Visual Studio:

• Open Visual Studio Installer.
  • Select Visual Studio Community and click on More > Repair.
  Reinstall Visual Studio:

  - If repairing doesn’t resolve the issue, consider uninstalling and then reinstalling Visual Studio.
  

Additional Tools

Windows Performance Analyzer (WPA):

• Use WPA to analyze performance issues during app startup.
  • Download and install the Windows Performance Toolkit (part of the Windows Assessment and Deployment Kit).
  DebugDiag:

  - Use Debug Diagnostic Tool (DebugDiag) to capture crash dumps and analyze them.
  
     - Download from the Microsoft website and follow instructions to set it up.
  

By following these steps, you should be able to identify the cause of the app crashing issue and resolve it.

Answer 2

Hello @Juan Juarez,

I suggest you first check the permission limitation.

You can try to run VS as administrator, see if it launches correctly. If you have antivirus, security management software, extensions installed, please make sure that they won’t block VS from loading and launching.

I would also suggest try to repair VS and reset VS settings.

You can repair VS from VS Installer(More > Repair), and reset VS settings by searching Developer Command Prompt for Visual Studio in Windows Search box > open it > run devenv /ResetSettings command.

If VS still fails to launch, try to run devenv /log command in Developer Command Prompt for Visual Studio. Reproduce this issue and navigate to %AppData%\Microsoft\VisualStudio\1x.0_<InstanceID> folder, check the ActivityLog.xml file. Share us the detailed error code and error message for further check.

Best Regards,

Tianyu
