Windows App Essentials (formerly Windows 10 App Essentials) 21.06.1 is now available (not available through Add-on Updater yet):
This version is in response to a potential scenario where users might install stable version of the add-on on Windows 11 (Insider Preview); Windows 11 support is experimental at this time. If this applies to you, a warning will be shown, reminding you that Windows 11 features can change without notice prior to general availability. If the add-on does get installed, NVDA will recognize Windows 11 and record this fact every time it starts. My recommendation is that you don’t install stable version of Windows App Essentials add-on until I tell you to.
Also, this is the last add-on release to support Windows 10 2004 (May 2020 Update), and don’t worry if the add-on still reports itself as “Windows 10 App Essentials”.
