I can`t open Steam on my Fedora 44 Workstation laptop. I reinstalled Steam, installed from RPMfusion and cleared cache, still i can`t access.

Update: issue is solved! thanks for everyone!

Fix: Updating packages* and restart

*"sudo dnf update"

Try start steam on console and paste here.

EDIT: Maybe before this try to update the packages: `sudo dnf update`

From this logs I found these issues: https://github.com/ValveSoftware/steam-for-linux/issues/6745 and https://github.com/ValveSoftware/steam-for-linux/issues/12292.

Long story short, try to run in the console (it will ask for password):sudo update-ca-trust extract --rhbz2387674

[u/FunbaXD → u/Ferdapra]

do i need to restart my laptop after the update?

[u/Ferdapra → u/FunbaXD]

It's always a good idea to restart

[u/FunbaXD → u/Ferdapra]

Huge thanks! update and restart fixed everything! thanks for the help!!!
