Wifi no longer working after upgrading to 5.4.1.arch1-1

After upgrading to the most recent kernel, I can't connect to my wifi router and when I run wifi-menu I get:

Scanning for networks... Could not read interface wlo1 flags: No such device
Could not read interface wlo1 flags: No such device
Could not read interface wlo1 flags: No such device
WEXT: Could not set interface 'wlo1' UP
wlo1: Failed to initialize driver interface
failed
No networks found

Then if I downgrade my kernel (5.4.1.arch1-1 => 5.3.7.arch1-1) and reboot, everything goes back to working.

Is there something I need to do to allow this update to work with my wifi chip?

Thanks.

Output of lspci

Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)

I'm not really sure what logs I should check. I'd have to upgrade again, check the logs then downgrade again and post the results. I can do that but it seems odd that this update would break this while previous ones didn't. I was hoping that someone knew why upgrading the kernel would cause this and how to fix it. The off the top of my head guess is that it has something to do with the firmware but am not sure. Thanks.

You can read the journal from previous boots. See the wiki for filtering journalctl.
