I've recently stopped using NetworkManger to manage my network and VPN connections as it seems to be a bit fiddly to get working with WireGuard.
Make sure all NetworkManager things have been removed.
systemd-resolvconf if you intend to use WireGuards
sudo pacman -S systemd-resolvconf
sudo systemctl enable systemd-resolved sudo systemctl enable systemd-networkd

sudo systemctl enable --now iwd.service.
This service messes about a little bit with devices so a reboot may be necessary here.
Finally configure the WiFi adapter with
