PyQt5 app compiled with PyInstaller using --onefile and --noconsole, but exe fails to launch

Question

Using Qt Designer and PyQt5, I have made a simple app that does some simple modifications on a.txt file and saves it. I successfully compiled my program using PyInstaller with the following command:

pyinstaller --distpath DESTINATION_PATH --onefile --noconsole myscript.py

The executable is created, but when I try to run it, I get an error saying that the application failed to start because its side-by-side configuration is incorrect . If I do not use the --noconsole, the executable runs fine but this is not how I intend to run it. I am fairly new to PyQt5 and PyInstaller, and I read somewhere that my program should not include "subprocesses" when using --noconsole but I am not entirely sure what that means. If of any relevance, my antivirus was deleting the.exe when compiled with --onefile --noconsole but not when only using --onefile. However, this issue was soon solved by creating an exception.

Here are the imports I use:

import sys, re, os
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QFileDialog, QApplication, QMessageBox
from pathlib import Path
import pyperclip as pc

Answer 1

The answer provided above by ThePyGuy has solved the issue. Adding hiddenimports=['pyperclip'] in the spec file was enough to prevent the error from occuring and the program ran fine to the extent that I tested it.
