Windows 10: Windows Sandbox doesn't exist on my Ryzen 7 PC.

I have a Ryzen 7 based PC, Virtualization is enabled in BIOS on an X570 motherboard. I use Windows 10 Pro 21H2, and I've tried to install "Widows Sandbox" under Windows Features and rebooted, but the app just doesn't exist on my PC.

Thanks for your answer, ken!

I deleted all my data. I had have it backed up.

I did a clean installation using the windows media creation tool (usb option).

After chkdsk, I close cmd and tried to boot and the laptop just turned it off. This morning I`ve restarted it and automatically windows did a repair. Windows has booted and it seems that the repair tool has removed chrome and acrobat pdf reader (the only two programs I had installed after reinstalling windows).
