arch linux – ArchLinux boot causes blank screen with blinking cursor into screen turning on and then off after failed update

The full context is that after some months of not booting into Arch, I decided to do it and do a full system upgrade with sudo pacman -Syu.
While upgrading my system, I also had Firefox open, which shortly after (While the upgrade was still running) asked me to allow it to restart, since it had just been updated. I did it and it reopened itself and all my tabs, however this caused my CPU usage to go to 100%, and a bit after that the screen turned blank with only a blinking cursor.

I rebooted my computer, and upon doing so GRUB showed me a “can’t find vmlinux” and “load kernel first” error.
I tried fixing it by getting into a installation medium, chrooting into my Arch partition and doing a sudo pacman -Syu from there, which at first I was unable to due to a “unable to lock database” error, which I solved by deleting it’s lockfile.
That being done, I asked pacman to reinstall the linux package, which it did successfully, but upon rebooting again an getting past GRUB, I now encounter the same blank screen with blinking cursor, followed by my screen turning off and then on a second later, and the process repeating.

I do wish to know if I can still salvage the system or if it would be easier to just delete the partition and reinstall everything.
