Same here on 6.2.8-arch1-1.
python --version returns Python 3.10.10
[EDIT]
I managed to run lutris from terminal by running “python /usr/bin/lutris”.

If you can run it like that, it indicates that something is wrong with your environment.

#! /usr/bin/env python3

This shebang is supposed to find your python interpreter from your PATH, or the environment (i.e. env will be in /usr/bin but the python interpreter could be in another location)

Your “python” points to the correct python 3 interpreter so it worked to launch lutris that way.

Do you actually have a “python3” in /usr/bin? The symlink may have been removed. If not, simply

cd /usr/bin
ln -s python3.10 python3
