Screensaver issue after April 2018 update

Hi All,
Today I decided to enable the screensaver in Windows 10 Pro. I already have the April 2018 Creator Update installed and seems to be working just fine. I got the April 2018 through the Windows Update on May 01 and installed flawless.
I set the screensaver to enable in 1 minute to test and set a password for my lock screen. I was assuming that when the screensaver kicked in and i moved the mouse then I would have to enter my password to get back into windows desktop. The password works fine on my lock screen when I log out and log back in. I have set the screensaver many times in the past and I find it strange the screensaver don't work anymore.
I can leave the screensaver enabled for an hr or more and go shopping and nothing happens. My desktop is still open on both my monitors.
Did something change in the April 2018 update to totally disable the screensaver or are there other places that require settings change to enable the screensaver?
What could be the problem for the screensaver to not activate at all?
Greatly appreciate any replies to resolve this issue.

cheers

I found the culprit and it was the Logitech M310 wireless mouse. I forgot I had this plugged in the back of my computer. I use that when I am streaming movies from my computer to the HDTV. When I unplug the adapter the screensaver works perfect. Anyone know how to fix this besides unplugging the Logitech adapter when not in use?
Searching for an answer didn't find a solution yet
Everything works fine, I just want my screensaver working also.

Well I finally figured it out. Knew it was something simple :) I removed the Logitech setpoint drivers and the software for the Logitech Solar keyboard and rebooted and all works well.
