hello everyone. 
i wake up to another morning when something just has to break. this time i know this is my mistake and i wish to report this because i dont know how to fix this.
its not like its the end of the world or anything, but today steam has stopped working for me. now, first of all, steam, as it is in SteamOS, is on autolaunch, obviously. but i didnt think how different it would be here in CachyOS, so i got curious and flipped the toggle in Steam’s settings “Run Steam when my computer starts” so that it stops launching. little did i know that this is the last time i will see steam function ever again.
on the next reboot, what i got both in wayland AND in X11 is just a flicker of a black screen, as if the server has died, killing all opened windows and everything, then it was all normal again, it restarted itself. but when i tried to launch steam, which didnt launch automatically on boot as i wanted, actually didnt launch at all, it gives me the same black screen and crashes everything. i googled a bit and found this:
though obviously im not running any flatpaks nor im on ubuntu so i cant just do what they said.
when launching steam-native this happens:
steam.sh[15457]: Running Steam on cachyos rolling 64-bit
steam.sh[15457]: STEAM_RUNTIME is disabled by the user (this is unsupported)
setup.sh[15507]: Steam runtime environment up-to-date!
steam.sh[15457]: Steam client's requirements are satisfied
CProcessEnvironmentManager is ready, 6 preallocated environment variables.

running steam gives basically the same except this at the end:
Steam Runtime Launch Service: steam-runtime-launcher-service is running pid 20028
bus_name=com.steampowered.PressureVessel.LaunchAlongsideSteam
these are on wayland btw. on X11 though, i cant even bring up the terminal because steam is still in CachyOS’s autolaunch somewhere, separately from steam the client, so the terminal just dies and it’s useless, so i have only one server functioning atm lol
so tl;dr basically something something steam-runtime-launcher-service what is it and how do i do the thing? and why was it so easy to break this?
i also dont like this line:
steam.sh[15457]: STEAM_RUNTIME is disabled by the user (this is unsupported)
is this supposed to happen? sounds scary
anyway i just tried deleting ~/.local/share/Steam/config/config.vdf to no avail
i have also tried deleting everything in ~/.steam/ and in ~/.local/share/Steam/ to no avail again
please someone help me… or not… its okay
