Research direction
Reproduce the failure in SteamOS Gaming Mode with a non-Steam Flatpak or installed game, then compare it with launching the same app from the desktop. Check the Steam client and SteamOS behavior around update 20260925.101; done means non-Steam apps launch from Gaming Mode instead of returning to the Play button without an error.
