You should install Go somewhere else than C:Users<username>go as that is also default GOPATH. Having GOPATH (a directory where your user modules are installed) in same place as GOROOT (a directory where Go itself is installed) will cause a lot of different problems and confuse many tools.
Either completely remove current installation and re-install Go somewhere else (recommended) or point your GOPATH somewhere else.
