How to fix Manjaro you are unable to boot, you need to load kernel first

I have a due boot system and one day after I updated my Manjaro system, I got this error:

file ‘/boot/vmlinuz-5.7-x86_64’ not found

you need to load the kernel first.

After some research, here I found the solution how to fix it:

The error was ultimately due to the fact that the Pacman has some change in the source code so if the IOS installation version is lower than 18.1.5 this error could happen.
