.NET Core 6部署Ubuntu 20.04时libSkiaSharp加载失败求助

开发的.NET Core 6应用在Windows 11本地运行正常，部署到Ubuntu 20.04服务器后，调用SkiaSharp时触发无法加载libSkiaSharp共享库的错误。已尝试以下方案均未解决：

• 更换SkiaSharp.NativeAssets系列包
• 调整发布目标运行时（Portable/linux-x64）
• 手动移动库文件位置
• 安装libfontconfig1
• 检查库文件依赖与权限

补充细节 #

• 项目通过SKTypeFace使用SkiaSharp处理文本，先后尝试SkiaSharp.NativeAssets.Linux与SkiaSharp.NativeAssets.Linux.NoDependencies包，均无效；未触发SKTypeFace相关代码时仍报错。
• 已确认项目引用包（[项目引用包截图]）
• 已检查libSkiaSharp.so文件权限（[权限检查截图]），权限配置正常
• 使用ldd命令验证库文件依赖，显示所有依赖均已存在（[ldd依赖检查截图]）
• 已安装libfontconfig1包
