Have you checked the permissions of specified folders? Have you added your user to the vboxusers group? See https://wiki.archlinux.org/title/VirtualBox.

[imrepentek]

/tmp is 1777 as it should be, there are no /tmp/.vbox* folders and yes my user is member of the vboxusers group

[imrepentek]

the issue is about vboxusers group not getting permissions, see the diff above

Why is no one else having issues then? "AI" hallucinations is not a solution.
