uniappx使用uts如何调用startActivity()启动应用

我在uts中接收到广播，并希望在接收时打开应用

export class Broadcast extends BroadcastReceiver {  
    constructor(){  
        super()  
    }  
    override onReceive(context: Context, intent: Intent):void{  
        context.startActivity(context(null, Class.forName('io.dcloud.uniapp.UniAppActivity')))  
    }  
}    

程序可以正常编译，但在真机调试 同步数据时会闪退

Caused by: kotlin.UninitializedPropertyAccessException: lateinit property currentApp has not been initialized  
at io.dcloud.uniapp.appframe.UniAppManager.getCurrentApp
