Gpedit.msc error (screen shoot attached)

ok, but Thanks anyway.
I thought its gonna work.
I ll reinstall windows if Im not gonna find anything

You could start by doing a Repair Install.
Repair Install Windows 10 with an In-place Upgrade
Reapir Install allows you to keep files, settings and apps.
No product key is required.
Activation is automatic.

If Repair Install fails to fix the problem, Clean Install is the only thing left I can suggest.

Backup files you want to keep first.
