"ImportError: DLL load failed while importing QtCore: %1 n'est pasune application Win32 valide" when installing .exe generated by PyInstaller

Question

I got the

Traceback (most recent call last): File "xxxx.py", line 10, in <module> ImportError: DLL load failed while importing QtCore: %1 n'est pasune application Win32 valide

error while I was trying to install a .exe that was created by PyInstaller. The weird thing is, only I got the error while others installed the software without any issues. How do I resolve this problem?

Re-downloaded and re-installed, still got the same problem

... reinstall the PyQt6 python if you use PyQt6 package with this argument --ignore-installed:

pip3 install PyQt6 --user --ignore-installed
