I read tens of related questions but none of them solved my issue.
Setup
Currently I'm using Python 3.9.12 in a conda environment (named 'plot_env', conda version = 4.13.0). For completeness here I show conda info and conda list output.

Minimal working example
import plotly.express as px
import plotly.io as pio
x = [1,2,3]
y = [2,3,4]
fig=px.scatter(x, y)
pio.write_image(fig, './figure', format='png')
After running this script the write.image() command freeze and the output in the terminal doen't show anything.
What I already Tried
Following some tips i found on the internet I tried:
Installing kaleido 0.1.0 : this just turned the problem to something else. When i try to run the script with kaleido 0.1.0 the output is the following
The kaleido executable is required by the kaleido Python library,
but it was not included in the Python package and it could not be found on the system PATH.
Searched for included kaleido executable at:
C:\Program Files\GitHub CLI
C:\Users\mirko\AppData\Local\Microsoft\WindowsApps
C:\Users\mirko\AppData\Local\Programs\Microsoft VS Code\bin
C:\Users\mirko\anaconda3\Library\bin
C:\Users\mirko\anaconda3\Scripts
C:\Users\mirko\anaconda3\condabin
C:\Users\mirko\AppData\Local\GitHubDesktop\bin
C:\Program Files\heroku\bin
So I added the specific path to my kaleido.cmd to Path, but this passage looks pretty sketchy to me because it means I will need to repeat it every time i create a new environment with kaleido installed.
This solved the issue: I exported the correct png image.
So my main question is: How do I solve this problem once and for all?
Using kaleido 0.2.1: nothing seems to solve the issue. The terminal just freezes and i can't use ctrl+C to print a log of the errors. I tried setting pio.kaleido.scope.mathjax = None but it did nothing.
Task manager info
I don't know if this might help but it looks like a lot of kaleido processes are running at the same time.
