Cannot run designer in pyqt5-tools

I'm trying to start qt designer in git-bash which provided by pyqt5-tools,
but have got the following error message (also see the attached screenshot):

> This application failed to start because no Qt platform plugin could be
initialized. Reinstalling the application may fix this problem.


The packages installed on the Windows 10 are:

PyQt5: 5.14.2



with Python version: 3.8.2.


Appreciate for any help.
