我用的是Android Studio 4.2.2。我创建了一个新项目，还没有添加任何东西到启动器代码，每当我点击构建或运行，我得到这个错误:

已安装的构建工具版本31.0.0已损坏。使用SDK管理器删除并重新安装。

我看了其他帖子的建议，但这些解决方案都不起作用。以下是我的尝试:

SDK Manager → SDK Tools → check "Show package details", uncheck 31.0.0, and click "Apply" → Uninstall 31.0.0 → check 31.0.0 and reinstall it In SDK Manager, deselect 31.0.0 and try installing an older version (e.g., I've tried 30.0.3) and update "buildToolsVersion" in build.gradle to the installed version Went to Project Structure → Properties and verified that 31.0.0 is selected for "Build Tools Version" and "Compiled SDK Version" Manually remove the stuff in the build-tools folder; i.e., rm -rf /path/to/android/sdk/build-tools/31.0.0 (it doesn't end in "-rc" like some other posts have described) Restart Android Studio Reinstall Android Studio

我是一个Android新手，只是想设置一个Hello, World!项目，真的不应该这么难。
