Importerror: Cannot Import Name 'Parametersource' from 'Click. Core'

I'm working on simple flask app, and I received this error
from click.core import ParameterSource
ImportError: cannot import name 'ParameterSource' from 'click.core' (/usr/local/lib/python3.10/dist-packages/click/core.py)
I don't know why it's appearing, because everything was fine and then just...
Here are versions I use:
black 23.1.0
click 8.1.3
Flask 2.2.3
Python 3.10.6
pip 22.0.2
I've been searching for solution and found that many people can't deal with this problem, and the only advice I found, is that I have to update Click and black to the latest version, but I'm already using the latest version.
What should I do? I there any any way to not use Click at all?
UPDATE
Here is how full error looks like

Please try the following steps:
pip uninstall black
pip uninstall click
pip install black
pip install click
You can soft reboot your server. Use
sudo reboot
Created another environment and launched my notebook there, I was able to resolve it this way.
Please try the following steps:
sudo apt purge python3-click
pip install click
I met the problem as the same. But when I changed the current working directory the problem disapper. Perhasp the click call the PWD as the first calling routine.
