Assuming that this is Ubuntu 20.04...

From the GRUB menu, choose Additional Options, then Recovery Mode, Root Access.

At the # prompt:

mount -o remount,rw /
sudo update-alternatives --config default.plymouth

Choose the ubuntu-logo choice, then repeat the command with the bgrt choice.

sudo update-initramfs -c -k $(uname -r)

Then reboot.
