After recently deploying Application Guard with Windows Defender Advanced Threat Protection using Intune configuration policies, Microsoft Edge is broken. Edge will open and then close. Edge will open in InPrivate browsing, but when you go to navigate to a website, it closes. Open Edge in Application Guard, everything is fine. As well as opening Application Guard window from an InPrivate session. Running on version 1803.17134.48. Tested on several devices with the same result. Not sure how to fix Edge. Have tried some of the recommended fixes, but nothing seems to work. Removed a device from Intune and turned off Application Guard, issue remains. Reset Windows and all is working until I re-enroll into Intune and the policies are pushed down to the device. The devices have supporting hardware and firmware. They are new Surfaces.
