Why can I no longer play Minecraft?

Yesterday I set up my pc again, but when I wanted to reinstall everything Minecraft did not work even though I logged on with the correct account via Microsoft, but where I would normally click on play it said "Play Demo". Before I put my PC on, everything worked and of course I bought the game too.

I would be happy if someone could help me, thank you in advance.
