Is it possible to recover ubuntu 20.04?

Somehow I ended with an unbootable system. I traced the problem to my /lib folder and possibly to other system folders

I currently have this ls -lsha lib lib32 lib64 libx32 usr/lib32/ usr/lib64 usr/libx32/

ubuntu@ubuntu:/media/ubuntu/8e5c9899-7541-4ab3-9577-27efa7337808$ ls -lsha lib lib32 lib64 libx32 usr/lib32/ usr/lib64 usr/libx32/

My libs folders are empty.

When I try to boot I get this end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100

I'm guessing the only solution is to reinstall the system. Am I correct?

My system partition is OK, I think. As well as my home partition. I ran fsck with no problem.

ubuntu@ubuntu:~$ sudo fsck -f /dev/sda5

I also executed boot-repair and I got this link https://paste.ubuntu.com/p/4CG9s4R9Dr/

Any help will be appreciated.

Is there any way to recover the missing system files?

FWIW I think the culprit was a bad Debian package I built myself or the checkinstall program for that matter when I was compiling emacs.

ubuntu@ubuntu:/media/ubuntu/8e5c9899-7541-4ab3-9577-27efa7337808/usr/local/emacs$ ls -lsha backup-070620211826-pre-emacs-27.2-custom.tgz 
30M -rw-r--r-- 1 root root 30M Jul  6 23:26 backup-070620211826-pre-emacs-27.2-custom.tgz

It has the same contents I have in my /lib folder.

The first thing that came to mind was to: Install a 2nd OS on the same partition, so it overwrites the bootloader, but that was right after I read that the sys is unbootable.
