settings won`t open

[GrahamPeacock-McHugh]

I`ve updated my pc and now i can`t open settings nor put pc into sleep mode, restart or shutdown. i`ve tried typing in search "settings" and clicked "open", it then closes straight away. Does anyone know how to fix the problem?

Try to reboot the computer and see if it happens again.

You can restart the computer or roll back to previous version.

@Cameron35 i tried restarting pc quite a few times and tried rollback twice. rollback kept failing. restarting pc doesn`t make a difference. only way i can use sleep, restart or shutdown is using task manager
