Dolphin File Manager does not work

When I try to open the Dolphin I’ve got this message:

dolphin: symbol lookup error: /lib64/ undefined symbol: _ZN12KQuickAddons12ConfigModule28passiveNotificationRequestedERK7QStringRK8QVariantS3_RK8QJ SValue

Can someone help me?

Edit1: I can’t open System Configs too…

if you build dolphin yourself that would go away. but that may or may not be quick to do.

The symbol is defined in /usr/lib64/, from the package kf5-kcmutils. Do you have the latest version of that package installed? Try dnf upgrade kf5-kcmutils, or a complete dnf upgrade and see if you have some updates.
