Because you are only testing maybe use an older distribution for #Ubuntu LTS?
OR

The answer says to enable Wayland. But does not say where to put those commands: Ctrl+Alt+T will open a terminal (command prompt-ish). The first line will open a hacker-like text editor. Do the edit and a menu in the bottom tells you how to save and close. "^" is ctrl key. Nano (the text editor) is made for computers without mice.

OK. You still have your windows working as it was?
With liveUSB nothing should happen but good practice always says to make backups.
There are several LTS (long term support) that slightly overlap in years you can upgrade from one to the next.
You can try another distribution like #linuxmint Or #fedora .
This is what default Ubuntu looks like:
