Manjaro failing to boot after kernel update

Hello! Ive just started using manjaro and after a kernel update it just stopped booting, looking at the system journal it is giving me these warnings:

I have been able to install the basic nvidia module through chroot (the same way i was able to access the logs) but not the other ones, other than that i can see no other traces of any packages causing it to have problems, the problem started with a kernel update to linux519 which i have removed and tried to put it back to the original linux510 and it still didn’t boot, so rn i am backing up as much data as i can from a live boot so if i can just reinstall the whole thing as a last resource

Thanks for the help in advance

from chroot run first update again:
sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu

I have done this before but i did it again and this was the response:

Rn i`m stuck on the live boot until its done uploading the backup so Im trying to do as much as i can before leaving it

ok, post output from:
mhwd-kernel -li && mhwd -li && mhwd -l

so uninstall the 414:
sudo mhwd-kernel -r linux414
and install the 5.15 kernel:
sudo mhwd-kernel -i linux515

do you have dual graphics, or only nvidia?

only nvidia

also it might be good to add that i have a windows install on another ssd, i don’t know if that changes anything

so additionally uninstall also the nvidia:
sudo mhwd -r pci video-nvidia-470xx
install again:
sudo mhwd -i pci video-nvidia-470xx
run these:
update-grub
mkinitcpio -P
exit
systemctl reboot
and hopefully you boot normally

It didn’t allow me to install 5.15, guessing its because live boot is running on it

ok, so reinstall the 5.10:
pacman -S linux510
then run the command from above - reinstall nvidia/grub/mkinitcpio…

alright I booted back to normal TYSM!
