What happened

Config folder is not being created and thus no app_settings.json is written when updating settings in the app.

Logs and stderr

When run as std::fs::write(app_settings_path,settings.to_string()).unwrap()

[2026-06-14T20:11:47Z DEBUG librepods::ui::window] Writing settings to /home/eron/.config/librepods/app_settings.json: {"stem_control":true,"theme":"Dark","tray_text_mode":false}

thread 'main' (163117) panicked at src/ui/window.rs:656:73:
called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Additional context

No response

Start in src/ui/window.rs at line 656, where settings are written to /home/eron/.config/librepods/app_settings.json and the missing-directory error occurs. Reproduce by changing a setting in the Linux Rust build, then verify that the config folder and app_settings.json are created and settings save without a panic.
