I do not use Steam so don’t know that much about this. @AngryPenguin would know more about issues related to Steam.
Was that an OpenMandriva (omv) package? FWIW looks like the steam package in OMLx 4.3 is dated 10-Dec-2021 so that could not be what you are talking about could it? I am fairly positive there have not been any OMLx package updates for OMLx 4.3 recently.
Reinstalling steam rpm?
Guess: It is possible that the system libraries in Lx 4.3 are to old for your steam client. You could try installing ROME. You can try upgrading Lx 4.3 to ROME but a fresh install is always preferred.
It is difficult to troubleshoot a problem if we don’t have logs or some kind of information that tells what user was doing and what happened. That is why we pinned this.
