After using gor --input-file, the program hangs indefinitely rather than closing.

My environment is Windows 10. When using the latest version 1.3.3, I execute the command gor --input-file requests0.log --output-http "http://192.168.2.44:446" --verbose 9. However, after requests0.log has been fully forwarded, the program remains running and does not terminate. If I only intend to run it once, shouldn't it conclude normally? Is this a bug or is it intentionally designed to keep waiting? #999
