代码示例

class A() {
    var first = true 
    var code = MutableLiveData("")
    @Composable
    fun Prepare() {
        Fun1()
        if (first) {
            Fun2()
        }
        first = false
        Fun3()
    }
    
    @Composable
    open fun Fun1() {
        //CODE 1 
        code.observeAsState("").value
    }

    @Composable
    open fun Fun2() {  
       //CODE 2  
       code.observeAsState("").value
    }

    @Composable
    fun Fun3() {  
       //CODE 3   
       code.observeAsState("").value
    }
}

class B : A() {
    @Composable
    override fun Fun1() {
        super.Fun1()  //去掉即可
    }
    @Composable
    override fun Fun2() {
        super.Fun2()
    }
}

现象：

如果在B 中override Fun1，同时调用 super.Fun1() 就会报上述错误。
