can't boot arch linux after installing with archboot on mac m1 with UTM

Hello
on Mac M1 and UTM,
I've tried to install arch linux with archboot.
https://gitlab.archlinux.org/tpowa/archboot/-/wikis/Archboot-Homepage


at first, setting the keymap didn't work so I skipped it.

After installing everything:
in the grub install it said it was successful then I got :

I tried reinstalling grub and efibootmgr and then tried to install the bootloader again.
This time I could see the grub.cfg file.

in the final phase, when installing grub, I got:

when rebooting grub goes up but then displays this message:

Tried looking it up.
Tried pacman -Syu linux

But then I get the error:

Tried looking it up but didn't manage to find a solution.

So I tried to reboot and go to grub.
in grub , using set:

using ls -l:


This is as far as I got and understand.

please help.
I would like to understand why it's so difficult installing arch linux in this way and why I get so many errors.

Start with debug.log and the Archboot/GRUB error messages shown in the report. Reproduce the installation on a Mac M1 with UTM, then determine whether the failure is in UTM or the Archboot/GRUB setup; done means a confirmed cause and a reproducible fix or a clear finding that it is outside UTM.
