Filters & Triggers => "Activate Preview" feature not working

[Dodutils]

Describe the bug
Activate Preview feature do not work and generate Pyhton error (copy added at the end of this message) it seems that some socket is used for a second usage with same network parameters which is not allowed.

=> "OSError: [WinError 10048] Une seule utilisation de chaque adresse de socket (protocole/adresse réseau/port) est habituellement autorisée" once translated in english it is "Only one instance of each socket address (protocol/network address/port) is usually authorized".

Then changedetection do not work anymore and you must kill and restart restart changedetection.py

Version
0.48.01

How did you install?
PIP3 Windows / Python 3.13 used

To Reproduce

Steps to reproduce the behavior:

1. Go to 'Filters & Triggers' for any web site you have
2. Click on 'Activate Preview'
3. 'Loading...' will appear but that's it
4. Error appear in the Pyhton console

! ALWAYS INCLUDE AN EXAMPLE URL WHERE IT IS POSSIBLE TO RE-CREATE THE ISSUE - USE THE 'SHARE WATCH' FEATURE AND PASTE IN THE SHARE-LINK!

Expected behavior
Should show the preview isn't it ?
