WinError 87 while running .exe file - Timych - Aug-06-2020

Hello everyone! Maybe it is an offtop but I am a bit puzzled.. Just generated exe file for my GUI python program for working with some geospatial data and use folium,geopandas,shapely etc. However, while running an error occured:

Error:
Traceback (most recent call last):

OSError: [WinError 87] The parameter is incorrect: ''
[17880] Failed to execute script main
The line number 11 in main.py is “import geopandas as gpd”

It looks like libraries conflict...

What is the reason?Are there any possible ways to resolve this problem?

Thanks for response and help!
