Please describe your issue in as much detail as possible:

Hello, when you first start Steam, it starts in a different language than the distro. I use PtBr Utf8, and Steam starts in English.
In Windows 11 it starts in PtBr.

I also wanted to make a suggestion: come with Proton stable enabled by default also in compatibility settings 😄

Steps for reproducing this issue:

1. Download the Steam client from the official website and install it with two clicks.
2. Start Steam and complete the final download steps
3. Steam starts in English on a system with the ptbr language

Success always
