Hello from Germany. I have the same problem. The install-button on windows store is hidden, since I deinstalled Minecraft. To play multiplayer, a Minecraft-update was required. A newer version was available, but I only knew that from the friend, i wanted to play with. There was no update for me, therefore I tried to install Minecraft new.
Supposedly, the problem is because the DirectX is not up to date.
I have DirectX12 an *11 is minimum required. crazy ... 😃!1.png!
Does that mean: I'm buying Minecraft because it meets the system requirements and with an update they get higher so that Minecraft becomes unplayable for a lot of paying people?
