To try out Linux Lite version 5.x go to
https://www.linuxliteos.com/download.php
Scroll down to the 'Previous Versions' section and chose the option to download 5.8.
Follow all the instructions to verify the download, copy to USB and install etc - very similar to what I assume you did to download and install 6.2.
After installing 5.8 from USB, run the updates to get all the 5.8 fixes.
If the system boots after updating, run the command
inxi -G
to confirm what hardware you have. Then post back.
Did you have to type in the errors messages in your original post by hand ?
