NEVERMIND, I fixed it myself

A while ago, I bought Minecraft: Java Edition for PC (OS. Windows 10)

After downloading launcher and logging into my account (with email and password), but the launcher demands me to pay once again. I clicked the button, which redirects me to minecraft.net website, but when I click buy there, I get redirected back to purchase page.

 

In attachments, there is screen on minecraft launcher and transaction confirmation
