I have steam installed from flatpak, and in the recent months this is what it outputs whenever I try to run it:

I have all the :i386 versions of nvidia packages I could find installed (nvidia-driver-460:i386 is not among them, sadly). Do I have to go back to mesa in order to have Steam working again? mesa and nvidia drivers don't work concurrently for me.
