Microsoft sandbox stoped working

Hi,



Thank you for writing to Microsoft Community Forums.



Please be informed that our developer team is aware of the issues with Sandbox and is working on resolving it. We do not have an ETA as of now, however I encourage you to send a feedback to our developer team via
Feedback hub. As a suggestion you can try disabling and enabling
the sandbox to check if that works. 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.
Your patience and understanding will be appreciated in this matter.



Regards
