Problems with pyinstaller doesn´t show all things that I created - python-3.x

Question

I've been working on an app to manage a little store with Python and SQLite. For GUI I used tkinter. I've written 13 Python scripts to make the app work. One of them call "principal.py" which imports most of the scripts and the other scripts import other modules like tkcalendar or xlwt (to write excel sheets), etc...
This is an example from "principal.py" first lines of code

This is how my files are structured and how it works when I run the script from vscode
But when I tried to make an exe from my little project using PyInstaller, it looks incomplete like this:
this is how it looks like when I run the exe file from the "dist" folder
I worked like this
Create the spec file with pyi-makespec principal.py
Re-write the principal.spec to save the database path
pyinstaller --windowed principal.spec
