Windows 10 going to sleep or locks after two minutes

Hi Everyone.
For the past few hours, it was noticed that our couple of windows 10 desktops go to sleep after two minutes.
After going to sleep here what I have seen there :

For reducing this issue
I Went to Advanced power settings, and I Click on the Change settings which are currently unavailable
I Click Sleep, then System unattended sleep timeout, then change these settings from 2 Minutes to 200 (no change))

The other thing which I had tried is the following :

Power Plan: I Turn off display 30 minutes, Put the computer to sleep (no change so I Changed to screen saver bubbles, wait 20 minutes, on resume display logon screen

I also did the GP track it seems to doesn’t work properly
I tried everything and I asked everyone about this but now it’s upon you guys, please suggest me
What to try next?
Thanks a lot
