c:\Users\[USER]\Downloads>Updated youtube-dl to version 2020.09.06.

Description

When I update youtube-dl with the -U argument, it'll fail to overwrite the old .exe with the new one.
What happens can be seen in the log above, and it's important to note that the last line ( c:\Users\[USER]\Downloads>Updated youtube-dl to version 2020.09.06.) isn't closed, before writing any more commands I need to hit Ctrl+C, because youtube-dl won't exit otherwise after an update.
The result is that when I run youtube-dl --version, I'll see that it's still the old version, and if I go to the directory in which youtube-dl is, I'll see that there is the old file from 2019 (in my case), and a new one made just a few seconds ago, named youtube-dl.exe.new

Same kind of issue here: When running
youtube-dl -U
from windows command prompt I see:
"ERROR: can't find the current version. Please try again later."
This issue also happened with version 2020-07-28 and is still alive

With --update --verbose I get some certificate error:
