hi i am liam i make a few projects and i i open unity hub i didnt see my projects anything gone there and i try hard to find can u pls help me thx

I am thinking the file isn't being detected by Unity. So what you do is press the button that says "Add" and locate the file location of wherever you saved your game. It should be a file named whatever your game was named, and in it, there should be folders labeled assets, packages, etc. Select that folder, and it should load it into Unity Hub.
