Unable to create KIO worker. Can not create a socket for launching a KIO worker for protocol ‘tags’

When I right click any file from Dolphin file-manager I’m getting “Unable to create KIO worker. Can not create a socket for launching a KIO worker for protocol 'tags'.” message. I can’t even drag and drop files/folders to trash. I’m on EndeavourOS KDE DE.

When Dolphin launched from terminal I’m getting errors like

kf.kio.core: KIO Connection server not listening, could not connect
kf.kio.core: couldn't create worker: "Can not create a socket for launching a KIO worker for protocol 'tags'."
kf.kio.core: ConnectionServer::listenForRemote failed: "QLocalServer::listen: Name error"
kf.kio.core: KIO Connection server not listening, could not connect
kf.kio.core: couldn't create worker: "Can not create a socket for launching a KIO worker for protocol 'thumbnail'."
kf.kio.core: ConnectionServer::listenForRemote failed: "QLocalServer::listen: Name error"

Did this happen after the update of 31-08 (version 26.08.0-5.1) ?
If it is not that version, maybe a update will solve things.

I’m not sure exactly from which version the issue is happening. I’m already on latest version of Dolphin.

Does this happen with a new user?

Found this topic on the KDE forum , don’t know if you have apparmor though.

AppArmor yes. I’ve also asked KDE forum, seems like it requires some additional configuration for Dolphin. I’ll re-check.
