Same error just happened with steam, when you right click in a game > manage > browser local files.

This is an integration issue in your OS; please report it to them. Thanks!

That seems like an assumption. Though, they were unable to reproduce the issue.

And as I didnt do anything related to this, unsure what is the cause of it. 


All packages seems to be installed.

❯ pacman -Qs kio
local/kio 6.9.0-1.1 (kf6)
    Resource and network access abstraction
local/kio-extras 24.12.0-1.1 (kde-applications kde-network)
    Additional components to increase the functionality of KIO
local/kio-fuse 5.1.0-3.2
    FUSE interface for KIO
local/kio5 5.116.0-1.2 (kf5)
    Resource and network access abstraction
local/kio5-extras 24.02.2-2.2
    Additional components to increase the functionality of KIO

I have found the cause, just not a fix while keeping the cause running.

Cause was AppArmor with one of it's profile. With the following command, I disabled it, and it worked.

sudo aa-teardown

To be more precise, the cause was a profile in the `apparmor.d-git` package.
