General

 * Games such as State of Decay 2 or Assassin’s Creed may hang or crash when launching.
 * Call of Duty: Modern Warfare and Black Ops Cold War may not launch starting with this build.

 * Some 32-bit systems may lose network connection after upgrading to this build.
 * When Xbox Game Bar is launched from the Start menu or via the Win + G hotkey while using a text editor, the computer may appear unresponsive. If you encounter this, dismiss the bar with the same hotkey and end the  process from Task Manager.

 * Miracast users may experience very low frame rates in this build.
 * Live preview doesn't work for pinned site tabs on some machines, a gray window is seen instead of the intended content.
