Raspberry Pi OS • lightdm boot failure

Using the prodedure outlined below, I created a 'Mint-like' system by installing cinnamon on RPI OS Lite. A year ago, it worked perfectly but now the resulting system fails to boot to the GUI because of a failure during the initialization of lightdm. I got around the problem by using raspi-config to select the GUI desktop with automatic login. Evidently, the problem is the lightdm-gtk-greeter which is avoided by using the auto login.

Procedure for creating a 'Mint-like' RPi OS:
using imager, install 'Raspberry Pi OS Lite (64-bit)' on an SD card
boot from the new image
sudo apt update
sudo apt full-upgrade
sudo tasksel (select cinnamon)
sudo raspi-config (and select)
System Options >> Boot/Auto Login >> Desktop - Desktop GUI, requiring user to login
Advanced Options >> Wayland - Switch between X and Wayland backends >> W1 X11
<Finish> >> <No> (don't reboot now)
sudo nano /etc/lightdm/lightdm.conf (and change)
greeter-session=lightdm-gtk-greeter.conf
user-session=cinnamon
autologin-session=cinnamon
<CTRL>O (Write out)
<CTRL>X (Exit)
