Several processes in uninterruptible sleep, reboot not fixing

I'm not a newbie but I didn't know where to post this.

My installation is semi-bricked sometimes. In particular, at the moment I can't run sudo commands or anything that touches the network or that command will add to the list of processes in a "D" state (which I gather means "uninterruptible sleep"). This means no chrome, no sudo kill, etc, but htop and journalctl work.

The process with the lowest pid in uninterruptible sleep is systemd-resolved. I attempted to run ping and that just added more systemd-resolved commands to the list.

I haven't updated anything too recently (at least a week or two, with reboots since. I think there may have been a fwupd in there but I'm not sure.

I rebooted twice, then booted to Windows (which worked), then booted again and everything was back to normal most of the day. Then I unlocked my computer from sleep this evening, did a couple things, and then Chrome froze and wouldn't force quit or close even when sigkill was sent.

The one pattern here is that it's only happened at the place I'm staying, where the wifi ssid is an emoji, and I noticed before rebooting after it froze that my network was connecting then disconnecting repeatedly.

I would post logs but I can't access them unfortunately, but I'm happy to report specific things as long as I can type them on my phone.

Any idea what might be going on?

Edit: I'm now fairly confident it's the wifi: I turned it off before logging in and now I can run sudo commands and open Chrome. Any idea how to report this to upstream (and figure out which package to report it in)? I'm using iwd, networkmanager, gnome, and systemd-resolved (I think that's everything, apologies if I forgot something).

That combination of networking packages read quite worrysome.

Unless you've done multiple deviating configurations for networkmanager, you need to disable and stop both iwd and systemd-resolved, otherwise you have a conflict with multiple network managers fighting for the network device. What's your output for

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
sudo journalctl -b
