Solutions

Replace with PlayerSettings.WSA.SetVisualAssetsImage(path, WSAImageType.UWPSquare44x44Logo, WSAImageScale._100).
Migrate all phoneAppIcon* scale variants at once.
Update plugins to versions targeting the current Unity API.

Example fix

// before
PlayerSettings.WSA.phoneAppIcon = "Assets/Icons/appIcon.png";

// after
PlayerSettings.WSA.SetVisualAssetsImage("Assets/Icons/appIcon.png", WSAImageType.UWPSquare44x44Logo, WSAImageScale._100);

Defensive patterns

Strategy: type-guard

Validate before calling

// Use the new setter for app icon at base scale
PlayerSettings.WSA.SetVisualAssetsImage(path, WSAImageType.UWPSquare44x44Logo, WSAImageScale._100);

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 phoneAppIcon assignments with SetVisualAssetsImage.
Maintain a legacy-to-new mapping for all phone app icon scale variants.
Update plugins after Unity version bumps.

When it happens

Trigger: Assigning to PlayerSettings.WSA.phoneAppIcon (the setter) in editor scripts, build automation, or post-processing. Usually encountered through reflection-based code or code targeting a deprecated API surface.

Common situations: Upgrading from Unity 5.x/2017 to a modern version; CI scripts that set the UWP app icon; third-party build tools that hard-code old property names.
