In Event Viewer (eventvwr.msc) under 'Windows Logs' -> 'System', a 'Warning' every 10 seconds when the 'Xbox (Beta)' app is running on Windows 10:

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 
{37399C92-DC3F-4B55-AE5B-811EE82398AD}
 and APPID 
{37399C92-DC3F-4B55-AE5B-811EE82398AD}
 to the user BTM-LEGION\btm SID (S-1-5-21-2978896364-2037134923-244970323-1001) from address LocalHost (Using LRPC) running in the application container Microsoft.GamingApp_2106.1001.9.0_x64__8wekyb3d8bbwe SID (S-1-15-2-1723189366-2159580849-2248400763-1481059666-1951766778-2756563051-3565589001). This security permission can be modified using the Component Services administrative tool.
 
 
 
 
 
 Ultimately in dcomcnfg I gave local launch and local activation to the special 'ALL APPLICATIONS' group
