I updating Manjaro and then crash, now i cant boot manjaro

[rodrigonrob]

When i in the UI to select boot, i select boot manjaro and then appear the next message:

You need to load the kernel
Manjaro cant found the kernel.
Press any key to continue...

The first message:

grub-probe: error: cannot find a GRUB drive for /dev/sda1.  Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sda1.  Check your device.map.
==> Mounting (ManjaroLinux) [/dev/nvme0n1p7]
 --> mount: [/mnt]
 --> mount: [/mnt/boot/efi]
 --> mount: [/mnt/home]

The second message with the error:

error: failed to commit transaction (conflicting files)
llvm15-libs: /usr/lib/libLLVM-15.0.7.so exists in filesystem
llvm15-libs: /usr/lib/libLLVM-15.so exists in filesystem
Errors occurred, no packages were upgraded.

How i can solve this?

[brahma]

use overvrite:
pacman -S llvm15-libs --overwrite "*"
then rerun the update again:

pacman-mirrors -f 5 && pacman -Syyu

if you get again exists in filesystem, use overwrite with the update command:

pacman -Syu --overwrite "*"

This work for me :

pacman -Syu --overwrite "*"

And then i found the kernel. Thanks!
