Can't boot my Rpi5 after upgrade

[grandcanyon]

I upgraded my RPI5 using pacman without any issues yesterday and then rebooted. I wag greeted with a completely black screen. I the read that I needed a blank config.txt which worked at least I could see something but it hangs at multi-thread users starting. It says OpenSSH and Network started but I did in arp scan and it doesn't show.

I then tried the vc4-kms-v3d and the vc4-fkms-v3d but these both hang at pwr_button. I checked my microSD with fdisk and it didn't report a problem. I also tried updating the firmware with no luck. Anyone know where else I can look?

Kernel package? Last-known-good version? Journalctl log?

I went from 6.6 to 6.18. I ended up pooching my system trying to fix it. I will have to reinstall anyways. I have a backup of my home kodi.
