Please describe your issue in as much detail as possible:

I use Steam on Arch with gamescope-session-steam for SteamOS-like experience on my HTPC. Its integration with NetworkManager started malfunction after today's client update and I'm no longer able to connect to any network, even though I see them being listed and I can also disconnect. Wifi network ask for password and then fails immediately, but same it cannot connect to a wired network. Using nmtui from tty I can connect to any network and then Steam session proceeds to work without any issue.

I can also reproduce the thing inside Plasma desktop using nested gamescope session initiated like bellow.

Steps for reproducing this issue:

1. Run standalone gamescope-steam session or nested with command

gamescope -w 1920 -h 1080 -f --steam -- steam -gamepadui -steamos

1. Disconnect from any network, works
2. Try to connect to any wired or wireless network, it doesn't work

Maybe there's some new requirement and I'm missing some package? Maybe it's a general bug? I think I haven't installed any updates, just the Steam client updated itself.

EDIT: initially attached logs from wrong machine, fixed.

Hmm, this is with IPv6 turned off completely for this connection, but changing it doesn't seem to make any difference.
