Unable to launch Surface Duo emulator in Windows 11

Hello samurai2083,
Thank you for using our Surface Duo Emulator and reporting the issue.

From the information you provided I cannot figure out what exactly is root cause,
but I can provide some documentation for you to follow then report back with other
information in case things are not fixed.
The way you are describing the emulator on the Surface Book 2, "the taskbar slightly opens as if an app is launching but then quickly closes" sound like the command prompt in which emulator is executed but fails, it could happen for a number of reasons: misconfigured Android SDK or hardware acceleration.
You can try to follow our installation instructions here: https://docs.microsoft.com/en-us/dual-screen/android/emulator/surface-duo-download?tabs=windows
Pay attention to the Android SDK installation, if it's in the default path or a custom one.
Then check the hardware acceleration guide for Windows here: https://developer.android.com/studio/run/emulator-acceleration#vm-windows

For debugging I would need to know the specific emulator version [SurfaceDuoEmulator_Android11_<VERSION>_windows.exe] you downloaded from here: https://www.microsoft.com/en-us/download/details.aspx?id=100847
Then, specify which Android SDK you are using, from Android Studio or Visual Studio, which versions and the specific paths where you installed them.
Specify if you configured the related Environment Variables or updated the pointer to the Android SDK.
In order to see the execution logs, don't start the emulator from the Desktop of Start Menu shortcuts, but instead open a Command Prompt, navigate to the directory where you installed the Surface Duo Emulator and execute the script called "run_SurfaceDuo2.bat". This way the prompt won't close in case of error, and you can copy and paste the logs.

Please let us know if any of the steps above fixed the issue, or if you have other questions.
Thank you!
