Unity Hub and Android Build Support Error

I am currently using Macbook Air with macOS Catalina. So I tried installing unity editor using the hub but after completion of the download, it shows error “Incomplete or Corrupted file”. I looked up for possible solutions to this problem on the forums but nothing worked and I wasn’t able to install the editor. So I tried to install it using the archive method provided by unity. I downloaded the torrent file with Android Build Support and installed it. Unity worked but android build support shows error now. In Preferences->External Tools it shows “Please download the recommended JDK using the Unity Hub” and similar for SDK and NDK. Now my problem is that as I wasn’t able to install the editor using the hub. Now I can’t add any module using the hub. So I can’t add editor using the hub and can’t add modules without the hub and now I’m stuck in this cycle and I can’t continue to use unity. Please HELP!!!

I have the same error, but with windows 10, unity version: 2020.3.17f1. I have android studio installed and updated. Any solution ?
