Just noticed that there was an issue with my mirrors earlier today and I missed a lot of package updates. Updated the mirrors using the tool on the welcome app, ran pacman -Syu and now my system seems to be a broken state. Where would I even start trying to fix this?
Something just occurred to me, I rebooted my machine the moment I saw the “reboot reccomended” desktop notification, and im wondering if it maybe wasn’t done with updates when that happened.
You might need to use your live usb to chroot into your installed system for any attempt at rescuing.
Following info are essential in order to let forum members to have an idea about your system:
Filesystem: EXT4, Btrfs?
Bootloader: systemd-boot, Grub?
mkinitcpio or dracut?
You could also post the output of the following commands from the live session:
sudo parted -l
efibootmgr
Filesystem is ext4, bootloader is grub, not sure what mkinitcpio or dracut are but from the chroot environment it seems like the first one is installed.
Output of sudo parted -l:

If you are already in chroot, try the following:
Update your system: pacman -Syu
Rebuild the initrds: mkinitcpio -P
Exit chroot by typing exit followed by enter.
It wouldn’t hurt to run a filesystem check to look for and fix possible filesystem corruption/inconsistency:
Launch Gparted. Right-click (double-tap if touchpad) on /dev/nvme0n1p1. Unmount it first. Next choose “Check” in the same menu and apply the operation in the tool bar.
If you get any error message at any of the steps above, post it on the forum.
If everything has been fine, cross your fingers and reboot.

Your system is installed in Legacy/MBR mode so the output of efibootmgr is not relevant in this case.
Thanks for posting though!
Worked like a charm! Thank you so much.
