Unity Hub 2.2.1 not downlading anything

Hello everyone!

I was trying to install Unity 2019.2.14f, but when I select the version and all the build things I want and hit done, nothing happens. No errors, no nothing! It just doesn’t install!

NOTE: I HAVE reinstalled unity hub a few times, and I have tried running it in admin mode

same problem here.
had to install separate version of unity from download archive.
