Initramfs unpacking failed: read error

I found this post: How do i chroot into my system and update my kernel
That explains how to do chroot, but I run into issues.

When I boot from live usb:
Manjaro linux - goes to the same error screen
under Advanced options for Manjaro linux
- Kernel 6.1.41-1 goes to the same error
- Kernel 6.1.41-1 (fallback) returns error: file /boot/initramfs-6.1-x86_64-fallback-img not found
and the press any key to continue does not work.
kernel 4.19.289-1- lets me load, but when I run sudo manjaro-chroot -a returns command not found
kernel 4.19.289-1 (fallback) also lets me in but sudo manjaro-chroot -a returns command not found
