KB4601315

Microsoft and Discord have found incompatibility issues with some games using Direct3D 12 when the in-game overlay feature of Discord is enabled. When attempting to open affected games you might receive an error, or the game might close silently.

To mitigate this issue, you can turn off the in-game overlay in settings within the Discord app.

This issue is now resolved in an update to the Discord app. To verify you're on the latest version, right click on the Discord icon in the notification area and select "Check for updates...". If there are updates to install, it should install automatically but you might need to select the arrow icon in the upper right corner of the app to install the updated version. There is no update for Windows needed to resolve this issue.

You might receive stop error 0x7E in nwifi.sys with a blue screen when you attempt to use a Wi-Fi Protected Access 3 (WPA3) connection. You are more likely to encounter this issue when reconnecting to a Wi-Fi network after disconnecting or when waking from sleep or hibernation. 

Note Most Wi-Fi networks are currently using WPA2 and are not affected.  

To mitigate this issue, you can do one of the following: 

• Update your device to Windows 10, version 2004 or Windows 10, version 20H2.

• Connect to a Wi-Fi network using WPA2. To do this you may need to reconfigure your access point or router settings.

• Connect using a wired ethernet connection.
