Steam fails to launch on Linux (KDE Neon)

[Led_Astray]

I installed Steam (for maybe 100th time) by using this command: sudo apt install steam.
Here's what I get by running LIBGL_DEBUG=verbose steam, as was suggested in a similar thread:
Running Steam on neon 20.04 64-bit
STEAM_RUNTIME is enabled automatically

Looks like steam didn't shutdown cleanly, scheduling immediate update check

P.S. I also tried installing Steam through "Discover" and it works fine except when I'm trying to import files to Blender, it doesn't see folders like "Downloads" that are normally there when I browse files through Dolphin. It sees "Pictures" and I could just drop everything there, it sees folders and files there but it's very annoying, I'd not want to use a workaround like this. Also when I rename or create new folders in Dolphin, these changes don't appear in Steam, and when I create new folders through steam, they don't appear in Dolphin.

Looks like a GPU driver problem. What distribution, what GPU (s), what driver version is it?

[Led_Astray]

Sorry, I installed Kubuntu and it works perfectly fine

[Plague Doctor]

I installed linux mint recently and am facing the same problem. Can't figure out for the life of me how to fix it. mine isn't even opening

[Marlock]

try to run

apt reinstall nvidia-XXX

where XXX

it might help fix any eventually missing 32-bit opengl or vulkan components from the Nvidia driver... on Ubuntu 20.04 I'm sure this kind of missing component happens, on Mint I've never seen reports but it's harmless anyway

[Led_Astray]

Oh yes, Kubuntu and some other distros actually had that message while installing steam saying you need 32-bit components
