Android Studio运行项目均触发java.lang.AssertionError错误求助

根据错误堆栈，该问题由**模拟器工具窗口管理器（EmulatorToolWindowManager）**添加模拟器面板时的断言失败导致。卸载重装AS无效的话，可尝试以下方案：

• 彻底清理AS缓存与配置文件
  关闭AS后，删除对应系统的配置目录：

  • Windows：C:\Users\<你的用户名>\.AndroidStudio<版本号>、C:\Users\<你的用户名>\.gradle
  • macOS：~/Library/Application Support/Google/AndroidStudio<版本号>、~/.gradle
  • Linux：~/.AndroidStudio<版本号>、~/.gradle
    重启AS后重新配置SDK与模拟器。

• 重置模拟器配置
  打开AS的Tools > Device Manager，删除所有现有模拟器，重新创建一个基础机型（如Pixel 5）的模拟器，再运行项目测试。

• 切换至AS内置JDK
  打开File > Project Structure > SDK Location，在JDK location选择Embedded JDK（AS自带JDK），避免使用系统JDK，应用设置后重启AS。

• 检查系统权限

  • Windows：右键以管理员身份运行AS，避免权限不足导致面板创建失败
  • macOS：在系统设置的「隐私与安全性」中，给AS授予「屏幕录制」和「辅助功能」权限

• 禁用第三方插件
  打开File > Settings > Plugins，禁用所有非官方插件（如汉化、主题类插件），重启AS后测试。

若以上方案均无效，可尝试下载Android Studio的Canary预览版本，该版本可能已修复稳定版存在的此bug。
