Microsoft is working on a resolution for a new issue causing the lid to crash on laptops if the lid is repeatedly closed and opened. This new issue affects devices running all Windows 10 versions in scenarios involving displays configured to run at 4K resolution. Microsoft doesn’t provide an estimated timeline and doesn’t say when exactly a fix should be expected to arrive. Microsoft also working on fixing a bug preventing Windows Defender Application Guard and Windows Sandbox from opening on devices running Pro and Enterprise editions of Windows 10, version 1903, 1909, and 2004.
