acpi package has zero elements CentOS 7 boot error

I advice you to start in rescue mode and access into mono user mode, this will give you the chance to extract the most value info from this server, after this you can build a new machine but based now on CentOS 8 which is more compatible with Ryzen CPUs.

As a work around, once you got acces in mono user mode and already make a backup of all your information, could you please check the status of this acpi=(on or off) the path for this is on /boot/grub2/grub.cfg and try to reverse it from the actual state.
