@conkerkh Can you please share some repro code? Also, try enabling debugger logs, see here for instructions: https://github.com/microsoft/debugpy/wiki/Enable-debugger-logs

@karthiknadig
to be honest this simple code can reproduce mentioned problem, it seems to be related to "input()"

if __name__ == "__main__":
    while(True):
        s = input()
        print(s)

[karthiknadig]

@conkerkh This occurs because of input(). Try adding "redirectOutput": true to your launch.json debug configuration, see #296 (comment). This was changed recently to allow better control of IO redirection.
