I've bought Minecraft Java but in my account it still says "BUY NOW" when I try to play using the launcher.

I bought Minecraft years ago. I was trying to play but it was showing an error about not being able to verify the purchase on my account, so I logged out and logged back in but now it says I dont have the game and asks to buy it. I also checked on the website and it says "We could not validate your access, please try to login again" I need this to be corrected as soon as possible.
