Windows 10: Windows Sandbox fails to initialize

I am trying to run Windows Sandbox on my machine but whenever I open it it just shows a popup with the message "Windows Sandbox failed to initialize". There isn't even any error code accompanying it. I did check my BIOS to see if I have virtualization enabled and yes I do.

Here are my PC specs:
AMD Ryzen 3550H with AMD Radeon Vega 8 Graphics
AMD Radeon RX 560X with 4 GB GDDR5 VRAM
8 GB DDR4 RAM

512 GB Micron NVMe SSD

Windows 10 Version 2004

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.
