Windows Sandbox does not open at all ?

Hi I have tried to launch Windows Sandbox, but it does not start at all. When I click the Sandbox icon, I only see the hourglass for a moment and then nothing happens. Sandbox simply doesn’t open. OS:__ Windows 11 Pro, version 25H2, build 26200.7840. What I have tried so far:

• Verified that virtualization is enabled, both in Windows and in the BIOS
• Enabled all the required Windows Features for Windows Sandbox
• Checked the system information using the systeminfo command
• I have also disabled Memory Integrity under Core Isolation to make sure it is not blocking hyper-v
• Edge browser was fully installed on my computer, and I didn’t do anything to trigger it.
• Power shell command: Get-AppxPackage MicrosoftEdge
• Microsoft.MicrosoftEdge.Stable Status ok I have not run any ‘debloat’ script

Edit: Running WindowsSandbox.exe from PowerShell shows an error message: (0x80070002)

I have enabled the following items in ‘Turn Windows features on or off’: – Hyper‑V and all of its sub‑components – Virtual Machine Platform – Windows Sandbox – Windows Hypervisor Platform

Using the systeminfo command: Virtualization‑based security: Status: Running Hyper‑V Requirements: A hypervisor has been detected. Features required for Hyper‑V will not be displayed
