为什么我得到“无法访问viewModelProviderFactory .. AppCompatActivity检查模块类路径是否缺少或冲突的依赖关系”

Question

我刚刚将以下依赖项添加到当前的Android应用程序中

implementation "androidx.activity:activity-ktx:1.1.0"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0"
implementation "androidx.lifecycle:lifecycle-extensions:2.2.0"
implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.2.0"

现在下面的代码显示了一个皮棉错误

    fun myMethod(activity: AppCompatActivity) {

...

          activity.startActivity(upIntent)
    }

如图所示

我已清除缓存并重新启动了AS，但是问题仍然存在

我正在使用此版本的AS
