Unpacking forever

[Kyo612]

I downloaded Forge for 1.15.2 (Mac) and installed it and found out most of my mods don't work with it. I deleted the download and the installation from the MC launcher. When I opened the newly installed file, it just got stuck like this. It won't move Can anyone help?

Had to clarify it wasn't the same file.
