Error with Mix compile and recompile command

Good evening, I’m having a problem using the command “mix compile” or “recompile”, every time I use it, it works the first time and then it doesn’t work anymore! Would you know what’s going on? I have already installed Elixir and Erlang by Windows 11 - Wsl with the newest version of Ubuntu and I am also a VMware with Ubuntu installed. I tried --force and it didn’t work either… I’m taking the course via Udemy and my teacher can’t help me either! I’m using Visual Code Studio and I don’t know if there’s a missing extension to be installed or if there’s an error in my Erlang and Elixir version! If you can help me I would be very grateful!

Yours sincerely,

Forget about Visual Studio for now.
Try running the command from the command line mix compile --force and share the output.

UPDATE: Please also include the output of elixir --version

Sorry i can’t upload picture about this problem because i’m new user. And i’m using VMware so i can’t copy and paste for here. But i can explain:

command: elixir -v
Erlang/OTP 24 [erts-12.2.1] [source] [64-bit] [smp:2:2] [ds:e:e:10] [async-threads:1] [jit]

Elixir 1.12.2 (compiled with ErlangOTP 24)

command: mix compile
command: mix compile --force
Compiling 1 file (.ex)
Generated fizz_buzz app

But when i try a test or when i call a print after compile with --force, i can’t see the new changes to my code!

So i don’t understand what’s happend. If i do all code and compile just in the end, its ok, but i can´t wrong because i can´t test during the programmation.

When I use the command: mix compile

nothing happens and is waiting for new command

In Windows with WSL i do this:

What do you expect to happen that is not happening?
