sdk - Flutter 光栅崩溃：FontStyle::registerLanguageList 中的 recursive_mutex 解锁崩溃

Question

最近，我的应用程序崩溃的许多用途，堆栈告诉我多线程同步出错。有人知道原因吗？

我的flutter SDK版本是Flutter 1.17.5 • channel stable，flutter Doctor结果是

[✓] Flutter (Channel stable, v1.17.5, on Mac OS X 10.15.6 19G2021, locale zh-Hans-CN) [✓] Android 工具链 - 为 Android 设备开发 (Android SDK 版本 29.0.3) [✓] Xcode - 为 iOS 和 macOS (Xcode 12.2) [✓] Android Studio (version 3.6) 开发

    [✓] Connected device (1 available)

以下是崩溃线程的完整堆栈跟踪详细信息：
