.NET MAUI无法替换默认紫色MauiIcon与MauiSplashScreen求助

我已将新的.svg图片添加到AppIcon和Splash目录，并将这些文件的Build Action设置为MauiIcon和MauiSplashScreen，但未生效。随后发现.csproj文件中已存在相关引用：

<ItemGroup>
    <!-- App Icon -->
    <MauiIcon Include="Resources\AppIcon\appicon.svg" ForegroundFile="Resources\AppIcon\bridgerecordicon.svg" Color="#512BD4" />

    <!-- Splash Screen -->
    <MauiSplashScreen Include="Resources\Splash\bridgerecordsplash.svg" Color="#512BD4" BaseSize="128,128" />
</ItemGroup>

以上两种操作均无明显效果。

根据微软文档说明：

在iOS上，启动画面会作为名为MauiSplash.storyboard的故事板添加到应用包中，并在Info.plist的UILaunchStoryboardName键中设置其值：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  ...
  <key>UILaunchStoryboardName</key>
  <string>MauiSplash</string>
  ...
</dict>
</plist>

因此，不应在Info.plist中设置UILaunchStoryboardName键，也不应向应用添加LaunchScreen.storyboard。

我检查了MauiSplash.storyboard文件，它似乎已引用更新后的启动图片：

但Info.plist文件中并未包含文档指定的条目：

    </array>
    <key>XSAppIconAssets</key>
    <string>Assets.xcassets/appicon.appiconset</string>
</dict>
</plist>

我手动添加了该条目进行测试，但仍无帮助。此外我还参考了相关问题，替换了相关文件，看似已重新关联，但仍无可见效果。恳请各位提供解决思路。
