Bug Problem while installing Unity Hub

Hey,

I can't install new versions of Unity. I tried to uninstall everything and clean the registry, but it still does not work. The hub downloads the file but then stops and the installation disappears. If I close the hub and reopen, I have a message telling me that the install failed.

This is what I am getting:
C:\\\\Windows\\\\system32\\\\cmd.exe',\n path: 'C:\\\\Windows\\\\system32\\\\cmd.exe',\n spawnargs:\n [ '/d',\n '/s',\n '/c',\n '\"\"C:\\\\Users\\\\shama\\\\AppData\\\\Local\\\\Temp\\\\unityhub-dddcc120-8d34-11eb-b3bd-9dda7ee39134\\\\UnitySetup64-2020.3.1f1.exe\" /S /D=C:\\\\Program Files\\\\Unity\\\\Hub\\\\Editor\\\\2020.3.1f1\"' ],\n cmd:\n '\"C:\\\\Users\\\\shama\\\\AppData\\\\Local\\\\Temp\\\\unityhub-dddcc120-8d34-11eb-b3bd-9dda7ee39134\\\\UnitySetup64-2020.3.1f1.exe\" /S /D=C:\\\\Program Files\\\\Unity\\\\Hub\\\\Editor\\\\2020.3.1f1' } ]","timestamp":"2021-03-25T06:42:01.365Z"}
