Hello, having some problems here and could really use help!

I received notifications about the kernel update today. But the installation was not possible due to a conflict of existing mesa-git packages. I decided to remove mesa-git and its dependencies, install updates, and download mesa as a replacement for mesa-git.

After these actions, the graphical shell stopped running. And there is no network connection! I can’t reinstall packages or download the graphical shell.

Running another kernel from grub failed. I don’t have a bootable flash drive. There is only a terminal and a second OS.

There is some information missing.

What happens if you try to boot a fallback kernel? Do you get any error messages?

This is likely the source of your woes.
Why were you using mesa-git?
Are you sure you properly replaced all necessary packages?
(note - you can find you package exchange history at /var/log/pacman.log)

Worst case scenario you can go here for chroot etc:
