Windows 10: Logon screen appearing prematurely

I have two machines both running Win 11 Pro latest update. Both machines are set to have a screensaver start after 30 minutes, which works fine on both. However, I have the same problem on both- the screen will change to the logon screen without warning, at intervals ranging from as short as a minute or so to several minutes of inactivity. This requires me to logon again, which is never a problem, just annoying to have to do. How can I prevent this?

Windows 10 Sleeps Prematurely

Your suggested step 1, worked temporarily. Computer is back to sleeping prematurely. Any other suggestions?

 

Lock Screen to Logon Credentials not working as desired

The recent upgrade(s) of my Windows 10 Pro sees Version 1709 and OS Build 16299.19 loaded. My original settings of not seeing the lock screen picture not appearing on the logon screen has seen the lock screen picture not being displayed at all, instead it is just a plain colour. However if I allow the logon screen to appear on top of the lock screen picture, then the lock screen picture is visible. A change the picture, even to one of the defaults, it still doesn't work as desired.

Suggestions to resolve this issue welcomed.
