steam installed both ways native steam pacman plus flatpak comvalvesoftwaresteam
i need both the flatpak has custom modifications that misbehave under the native install
problem flatpak steam fails with
bwrap cant find source path procselffd25 no such file or directory
always fd25 steamwebhelper then crashes
reproducible trigger with the native steam package removed the flatpak works
reinstalling native steam breaks the flatpak again confirmed twice
already tried no fix
reinstalled p11kit lib32p11kit nss lib32nss cacertificatesutils plus updatecatrust
flatpak repair cleared runuseruidflatpakhelper and runuseruidp11kit reboot
p11kit listmodules clean and p11kit server provider p11kittrustso worked standalone
fd25 is not captured by flatpak run v 21 grep nor by a script capture of a 25s client launch
flatpaks own sandbox starts fine xdg dirs and tz get set so the error seems to come from steams nested runtime not flatpaks outer bwrap
