Please describe your issue in as much detail as possible:

Expected to happen: steam client runs, what actually happened: it does not run
~$ steam
steam.sh[60417]: Running Steam on linuxmint 21.3 64-bit
steam.sh[60417]: STEAM_RUNTIME is enabled automatically
steam.sh[60417]: Runtime checksum: d41d8cd98f00b204e9800998ecf8427e steam-runtime.tar.xz, expected
steam.sh[60417]: Unpack runtime failed, error code 2
steam.sh[60417]: Error: Couldn't set up the Steam Runtime. Are you running low on disk space?
/home/es/.steam/debian-installation/steam.sh: line 89: LD_LIBRARY_PATH: unbound variable

Steam has been working for ages so I'm not sure whats changed, I was briefly on mint 22 and the same thing happened, have tried un and reinstalling, and it's not a storage issues (400gb free)

steam.sh gist

Steps for reproducing this issue:

  1. Run 'steam' command in console/click on steam shortcut

(very sorry I am not very good at linux so if anyone does have solutions clear instructions would be very appreciated)

I found things that seem to stop the unbound variable part but then i just get a popup with "Error: Couldn't set up the Steam Runtime. Are you running low on disk space?" instead :/

AH turns out there were 2 different folders inside .steam with steam.sh and stuff, and deleting debian-instalations seems to have let it run, remake the folder and sort itself out, i think its fine now???

Nothing extracted yet.
