WiFi device not detectable after 6.11 update

(I am using a ThinkPad T14 Gen5 AMD Ryzen)

I ran sudo pacman -Syu yesterday. Today, I noticed that I couldn't connect to the internet (I usually use nmcli).

When I run nmcli, my WiFi card--or whatever it is called--(wlan0) doesn't show up anymore:

enp2s0f0: connected to Wired connection 1

Use "nmcli device show" to get complete information about known devices and
"nmcli connection show" to get an overview on active connection profiles.

Consult nmcli(1) and nmcli-examples(7) manual pages for complete usage details.

You can see that I am currently using my ethernet connection at the moment.

iwctl + device list reveals absolutely nothing.

iwconfig:

lo        no wireless extensions.

enp2s0f0  no wireless extensions.

wwan0     no wireless extensions.

I have tried reverting back to an update below 6.11, but I kept having conflicts between pacman and yay, and I dug myself into a hole I couldn't get out of. This was the error after changing my mirror link to one I found in the archive from before 6.11, and then running sudo pacman -Syyuu:

resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: installing pacman (6.0.2-7) breaks dependency 'pacman>6.1' required by yay

So, I changed my mirror back to the current one and re-ran sudo pacman -Syu.

I am not quite sure where to go from here or how to fix the issue. Any help appreciated. Thanks.

Re: WiFi device not detectable after 6.11 update

Could you try if downgrading to this package fixes it?

sudo pacman -U https://archive.archlinux.org/packages/l/linux/linux-6.10.10.arch1-1-x86_64.pkg.tar.zst

Also could you post a full dmesg?
