Try to disable vGPU from Group Policy.

Open gpedit.msc, go to "Computer Configuration > Administrative Templates > Windows Components > Windows Sandbox"

and set to "Disable" the following option:

"Allow vGPU sharing for Windows Sandbox"

Then restart and re-try

Let me know

Hi Alvise,
thank you again for your support and expertise regarding the Sandbox configuration.

I wanted to bring up an additional issue I’ve encountered: my integrated webcam does not appear to function within the Windows Sandbox environment. I have verified the privacy settings and activation options, and everything seems to be configured correctly. Additionally, I’m not receiving any error messages related to the webcam.

Interestingly, both the speakers and microphone work perfectly fine within Sandbox—it’s only the webcam that refuses to activate.

Could you please provide any suggestions or solutions to address this? I appreciate your time and help as always.

I applied the advice. No behavior changes.
