Error message when trying to connect to NFS

SUMMARY
I set up several NFS connections to my home server in Dolphin using Fedora 39 (and Plasma 5.27.1 If I recall correctly). On Fedora 39 I could always access my NFS shares via the bookmarks or by typing `nfs://192.168.2.202/export/music/` on the location bar. 
After updating to Fedora 40 (Plasma 6) I can no longer access my NFS shares via the bookmarks nor via the location bar and I get the following error message:

"Unable to create KIO worker. Unknown protocol 'nfs'."

STEPS TO REPRODUCE
1. Set up a connection to a NFS share in Fedora KDE 39  (and Plasma 5.27.1 If I recall correctly) by typing `nfs://IP.ADRESS` on the location bar of Dolphin. Dolphin connects to the NFS share. OPTIONAL: save this connection as bookmark on the Places panel
2. Update to Fedora KDE 40 using `sudo dnf system-upgrade download --releasever=40` as recommended in https://docs.fedoraproject.org/en-US/quick-docs/upgrading-fedora-offline/#sect-performing-system-upgrade
3. Try to connect to the same NFS share as in step 1, either via bookmark or by typing `nfs://IP.ADRESS` on the location bar of Dolphin.

OBSERVED RESULT
Dolphin fails to connect to the NFS share and returns the following error message: "Unable to create KIO worker. Unknown protocol 'nfs'."


EXPECTED RESULT
Dolphin connect to the NFS share.
