Solutions

Replace with PlayerSettings.WSA.SetVisualAssetsImage(path, WSAImageType.UWPSquare44x44Logo, WSAImageScale._150).
Migrate all phoneAppIcon* variants at once to prevent mixed old/new API usage.
Replace stale plugin DLLs with versions compatible with the current Unity API.

Example fix

// before
PlayerSettings.WSA.phoneAppIcon140 = "Assets/Icons/appIcon140.png";

// after
PlayerSettings.WSA.SetVisualAssetsImage("Assets/Icons/appIcon140.png", WSAImageType.UWPSquare44x44Logo, WSAImageScale._150);

Defensive patterns

Strategy: type-guard

Validate before calling

// Use the new setter for app icon at ~140% scale
PlayerSettings.WSA.SetVisualAssetsImage(path, WSAImageType.UWPSquare44x44Logo, WSAImageScale._150);

Type guard

static bool IsDeprecatedWsaProperty(string name) =>
    typeof(PlayerSettings.WSA)
        .GetProperty(name,
            System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static)
        ?.GetCustomAttribute<ObsoleteAttribute>()?.IsError == true;

Prevention

Replace phoneAppIcon140 assignments with SetVisualAssetsImage using WSAImageScale._150.
Audit imported packages for stale app icon property references.
Use the unified API for all app icon scale variants.

When it happens

Trigger: Assigning to PlayerSettings.WSA.phoneAppIcon140 (the setter) in editor scripts, build pipelines, or post-processing. Encountered most through reflection-based code or stale API references.

Common situations: Migrating a UWP build pipeline from an older Unity version; CI scripts that set app icons at multiple scales; third-party packages with stale property references.
