Dynamic Component authoring is not included in SketchUp Make (BTW, the newest Make version is 2017, not 2021). Make only has the Interact and DC Options functions.
Not sure what is going on and still (as others mentions) not sure what version you are running, but why do you want the toolbar? Is there something that you are trying to do that is not working through the comtext menus?
Sounds like a faulty install.
Find (or download a new copy) the original installation .exe select it, right click and choose Run as Administrator, follow the prompts and when given the option select Repair. Once done restart your computer.
