first, I transferred my account from mojang to Microsoft

then I deleted the game and tried to download it and I got a windows update error, but I coped with it

 now, having downloaded the game from the Microsoft Store, it shows the "demo version" button, and I have a licensed Minecraft Java

I deleted the game again and downloaded it from the Minecraft website (and I deleted the .minecraft folder) and I have the same problem

when i try to install forge it says to me that "run Minecraft at least once"
