I bought Minecraft Java Edition, activated the code, but after reinstalling Windows, I need to buy it again.

On April 29, 2021, bought Minecraft Java Edition from Instant Gaming store. They sent a message with an activation code. Activated at https://www.minecraft.net/ru-ru/profile/redeem, downloaded and played. And my account is tied to a Microsoft account.

Then I needed to reinstall Windows. Again logged to the Microsoft account on https://www.minecraft.net. I downloaded the game, but I could not install it with an error Microsoft Store:

Minecraft Launcher is currently not available on your account. Check if you entered the Store and try again. Here's the error code if you need it: 0x803F8001.

The game was purchased, activated, and after reinstalling Windows, it asks to buy it again. What is it? I tried to reactivate the code in minecraft.net, but writes that the code is activated. Tried it at https://redeem.microsoft.com/?wa=wsignin1.0, but there it asks to activate it in another web service (meaning minecraft.net). But it is activated and I can still download the full version, but the Microsoft store does not allow installing, giving an error.

What to do? How to link the game to the Microsoft account again, if it was originally tied when I logged into minecraft.net through the Microsoft account, before reinstalling Windows?
