Question endless loading of unity hub

Good day,
I used to use Unity and Unity Hub without any problems. But yesterday, when I tried to install a new version of unity after a few minutes of downloading, I saw some error, after which I saw that the memory on my hard drive C is full. And Unity Hub does not open, there is only endless loading in the window. After I tried to delete from the hard drive With and reinstalled to another hard drive that is empty. Installed. And now the same problem, I can't start Unity Hub, the download is endless.
