이것은 버그 인가요? 윈도우 환경에서 디렉토리 이름에 ":"가 들어갈수 없어서 발생되는 현상으로 보입니다. ubuntu 에서 같은 방법으로 진행시 에러가 발생하지 않습니다.

is this a bug? It seems to be a phenomenon that ":" cannot be entered in the directory name in the Windows environment. When proceeding in the same way in ubuntu, no error occurs.

It seems to be a bug yes because your registry specified a port. Will take a look at this one.
