Please describe your issue in as much detail as possible:

Expect Steam client to launch.
Instead Steam errors out on startup.

Steps for reproducing this issue:

  1. sh -c steam
Kkisak-valve maintainer 2025-02-02 github

Hello @ziqul, I suspect that error is related to the . in your home folder name. Can you create a temporary local user with plain ascii for the home folder and test if that has an effect?

Zziqul 2025-02-02 github

@kisak-valve, creating new user without . in its name helped indeed. Thank you very much for quick response.

Can you please point out how you came to this conclusion? Was it because filsystem_stdio.so spelled incorrectly? What did that tell you?
