Microsoft says it's looking into reports that apps including "Hey Cortana" and Google Chrome hang or freeze for those who have installed the recent Windows 10 April 2018 Update.

The company suggests trying the Windows logo key + Ctrl + Shift + B to wake the screen or, for laptop users, opening and closing device lid, in an attempt to resolve the issue.
