missing modules (cat /proc/modules; ls /dev) dev/mapper does not exist

I had encountered an issue. I manually installed an older kernel version (linux-image-5.4.0-48-generic) using apt install linux-image-5.4.0-48-generic. Installation was successful, execute update-grub and update-initramfs -u -k all without any error.

When I reboot, i got the error as shown.:

Error from grub boot

Have anyone encountered this issue before?
