18.04.4 kernel update locks up boot

18.04 kernel update from 5.3.0-46-generic to 5.3.0-51-generic

5.3.0-46-generic will boot from grub menu and works fine

5.3.0-51-generic will not boot and it stops here

do i have to uninstall 5.3.0-51-generic and reinstall ?
sda1 /boot/efi
sda3 is my /
sda2 /swap
how would i completely remove 5.3.0-51-generic and reinstall ?

dpkg -l | grep linux-image-.*-generic
sudo apt-get install --reinstall linux-image-5.3.0-51-generic
