Unable to switch kernel version because of nvidia-utils

Ok so everything is working fine now, I managed to update my kernel and now I can update my manjaro without any problems.

For anyone wondering how, here are the steps I followed :

  • Create a LiveUSB Manjaro (use the latest ISO from the official download page, be sure to check the kernel version of it, personally I needed the 5.15 version).
  • Boot on it.
  • Open a Konsole as root and run manjaro-chroot -a (The -a flag will automatically detect any Linux filesystem on your devices and mount them on /mnt)
  • From the chroot env, install the new kernel with pacmanpacman -S linux515 for my case (mhwd-kernel -i linux515 won’t work in a chroot env).
  • Reboot on your Manjaro and press Esc. in order to choose which kernel you’ll use.
  • Uninstall the old kernel → sudo mhwd-kernel -r linux513.
  • Uninstall the video driver → sudo mhwd -r pci video-nvidia in my case.
  • Reboot and run sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu.
  • Reinstall the video-driver via the GUI and reboot.

With theses steps it should work.

Many thanks to @Mirdathos and you guys for your help & speed.
