Microsoft working on a fix for Windows 10 Sandbox failing to open

[silversurfer]

Microsoft is investigating a known issue preventing the Windows Sandbox and Windows Defender Application Guard (WDAG) from opening on some Windows 10 devices.
 
Windows Sandbox allows Windows 10 users to run applications within a completely isolated desktop environment, separately from the host machine.
 
WDAG protects Windows 10 and Microsoft Edge users against emerging online attacks while they are browsing the Internet by opening untrusted sites within isolated Hyper-V-enabled containers.
 
According to a support document published by the company earlier today, the two apps will throw the following errors after failing to start on affected systems:
• ERROR_VSMB_SAVED_STATE_FILE_NOT_FOUND (0xC0370400)
• E_PATHNOTFOUND (0x80070003)
