Hello
This seems to be a known issue with certain versions of Windows 11, where the Explorer in Windows Sandbox doesn’t work properly and results in a black screen after a few seconds.
Here are a few potential solutions you could try:
Check if Windows Sandbox is enabled: Some advanced features on Windows 11 are disabled by default, including Windows Sandbox. You’ll need to manually enable Windows Sandbox from the Windows Features dialog to use the feature. If Windows Sandbox is already enabled, try to disable and re-enable it to see if that helps resolve the issue.
Check if the Windows Sandbox associated services are running: Windows Sandbox needs the Hyper-V Host, Hyper-V Time Synchronization and the Virtual Disk service to be running to work. If one or more services are stopped, it may fail to start.
System repair tools or system restore: If the issue persists, it may be a case of corrupt or damaged system files. You can use the built-in system repair tools or perform a system restore to undo recent changes to your system.
