Windows 10: I cant use Windows Sandbox - Blinking Display

Hello everyone,


I am unable to use the Sandbox.

It starts, but when it opens, it's just blinking every 2 seconds. You cannot click on anything inside the Sandbox.


I dont have Hyper-V, Hypervisor, or Container installed. And the known "solutions" like the 100% scale also didn't work.


What can I do?


I already removed Sandbox some months ago and now after the latest cumulative Update I made today, I retried the same thing, but it still wont work.

:)

There is a possibility that the feature is corrupted or not set up properly. I would advise you to disable Windows Sandbox first and then enable it. Please follow the steps mentioned below:

1. Open Control Panel.
   
2. Then click on all Control Panel Items.
   
3. Then click on Programs and features.
   
4. Then on the left hand side, click on Turn Windows features on or off.
   
5. Then uncheck the option: Windows Sandbox.
   
6. Then restart your computer.
   
7. After restart, please enable it and check if the sandbox is working.
   

Also make sure that you meet all the requirements for Windows Sandbox.

Blinking Screen

Blinking screen issue is usually caused due to Video card drivers.

I suggest you to try updating the Display Adapter drivers check if it works for you.

Follow the steps to update the Display driver:

• Press Windows Key + X key and click Device Manager.
• Expand ‘Display Adapters’.
• Right-click on the Display Adapter listed and click on ‘Update Driver Software’.
• Select the option to automatically search for the updated driver software.
• Restart the computer after its updated and verify.

Also try to access the computer manufacturer's website and download the latest display drivers for your computer and install the same.

If issue still persists, I suggest you to Uninstall and reinstall the Display driver and check if it works for you.
Refer to the steps below:

Follow the steps to uninstall the Display driver:
