Quick Fix: Open an instance of Visual Studio Code as a normal user. Launch a second instance with code --no-sandbox --disable-gpu-sandbox

The Solutions:

Solution 1: Launch VS Code with `–no-sandbox` and `–disable-gpu-sandbox` flags

To resolve the issue, launch VS Code with the `–no-sandbox` and `–disable-gpu-sandbox` flags. These flags disable sandboxing, which can cause problems when launching VS Code in admin mode. To launch VS Code with these flags, follow these steps:

  1. Open an instance of VS Code running as a normal user.
  2. In the terminal, run the following command: `code –no-sandbox –disable-gpu-sandbox`

Solution 2: Run with No Sandbox Option

Due to process sandboxing, running Visual Studio Code in administrator mode is currently unsupported when AppLocker is enabled. To bypass this limitation, launch Code with the following command:

code --no-sandbox --disable-gpu-sandbox

However, note that this workaround is only available until VS Code 1.79.2 is released. For a more permanent solution, you can subscribe to issue #122951 on GitHub for updates.
