I tried "Dim" and "Black" and it comes back normally.

I'd suggest trying another screensaver which is not a default one.
I'd also suggest trying to start from scratch and seeing if DCS will cause the same problems. There was a simple procedure where you would rename the Kodi folder (If I remember correctly) which would make your Kodi start from scratch. When you're done testing you delete the current Kodi folder and rename back the original one.

Good thinking.
I tried with a different not-default screensaver and Kodi restarts as well!!!

So it is not related to DCS. Thanks for that.

I'm glad that you've gotten to this point, just keep in mind that something is broken with your Kodi.
Try starting from scratch (like I wrote already) and try to figure out what exactly causes your issues. Install addons one by one and you'll find out what's the problem relatively quickly.
