Can't use Nimble on Windows 10
Hi, sorry if it's not good place to report. Installed Nim recently using instruction from the official website. Compiler itself works fine, was able to start doing some tutorials and compiling tools, `nimpretty` for example. Plugins for VS Code work as well without any issues. The only thing is not working is package manager. Tried to run it through `cmd` and Git Bash, no output, no errors, nothing. Check the screenshot:

I also disabled antivirus/Windows Defender/checked firewalls just in case. And tried to run the same things as administrator. Tried to build `nimble` with `koch`, which was done successfully. Issue persists.

Any ideas how to debug this?
