Problems happend when trying to transform a VGroup object to another VGroup object

[ttzytt]

Describe the error

I have two VGroup objects, which consisting of other VGroups and Mobjects, when I trying to apply a ReplacementTransformation to these two VGroup objects, some errors happend

Code and Error

Code:

        case_1_scene = VGroup()
        case_1_scene.add(
                        case_1_vised_gird,
                        new_line,
                        case_1_explaination,
                        case_num_txt,
                        left_plug,
                        right_plug,
                        show_no_plug_on_left_right
                        )
        
        
        del visited_grid_id
        del vgrp_grid_line_list
        vgrp_grid_line_list = (creat_grid_line(5, 5, 1, color=BLUE_E))[1]
        case_1_overall_grid = (creat_blocked_grid_by_id(4,4,1,1,2))[1]
        case_1_overall_vised_gird = (creat_visited_grid(4,4,1,
                                                *(tuple(range(1,10))),
                                                color=GREEN_E,
                                                fill_color=GREEN_E,
                                                fill_opacity=0.6
                                                ))[1]
        case_1_overall_effect = VGroup(
                            vgrp_grid_line_list,
                            case_1_overall_grid,
                            case_1_overall_vised_gird
        )
        
        self.play(ReplacementTransform(case_1_scene, case_1_overall_effect))

If I change the code in the last few lines to this:

self.play(ReplacementTransform(case_1_scene, vgrp_grid_line_list))
self.play(Write(case_1_overall_effect))

Then it will run properly, and their will be a similar effect, but I just confused about that error
