There is nothing in dmesg or the system log to provide additional clues as to what file descriptor isn't being mapped.

Does this issue reproduce with native Steam No

This is a regression in the client_beta branch of "Steam Linux Runtime 2.0 (soldier)" and "Steam Linux Runtime 3.0 (sniper)". I'll try to fix it in the next beta of each one. See https://github.com/ValveSoftware/steam-runtime/issues/644.

As a workaround, go back to the the default (non-beta) branch of each of those compatibility tools.

This is a Flatpak-specific issue.

The error pressure-vessel-adverb[...]: E: Unable to receive --assign-fd source 6: Bad file descriptor is fixed in today's betas (labelled 0.20240125.x in SteamLinuxRuntime_*/VERSIONS.txt).

fixed in today's betas (labelled 0.20240125.x)

These betas have now been promoted to stable releases, so I believe there is nothing to be done here. Please could @eeyrjmr or a maintainer close this?
