Legends of Runeterra - not working

I was always able to install/run LoR on my various Linux distros.
Since a couple of weeks, this is no longer true - the installer somehow works, it crashes near the end but closing the RiotClientServices demon does the job.

The game, however, refuses to launch. On my EndeavourOS, which already had the game installed, I was able to make it run by running it in a Virtual Desktop, but that’s the only machine in which I can manage to do that.

On my Debian 12, no way - install crashes, game doesn’t launch.

Does anyone else have the same issue? Do you have suggestions?
