get in trouble: Failed to setup debugger environment

[ghost]

Hello, please help me ! I don't know how to fix it. I created a hello_world erlang project without rebar3, and a main.erl, and a function start() -> io:format("hello erlang~n")., it can be runned but cannot be debugged, and the following error message occured in debug window:

Failed to setup debugger environment

Thanks a lot!
