Bought Minecraft, Launched Minecraft Launcher, Says I can only play the Demo and I need to buy Minecraft-again.

I got a new laptop fixed, I am trying to play Minecraft on here. The problem is that I bought Minecraft, the Minecraft Launcher App downloaded and I opened it and it said I could only play the Demo version of Minecraft Java Edition. (All this after spending $60 on the wrong Minecraft version which was for Windows 10 so now I am out $60...) I am just trying to play Minecraft now every time I open the launcher it tells me to buy the Java Edition and when I click the link it says "already have the game? redownload it. Instead of giving me the option to sadly, spend another $26 like I had already done.

If you're an employee and need verification for my receipts of the purchases of Minecraft I can provide everything I have recent from this incident. (Also I don't know what Affects Version/s this is so I just picked a random one.)
