Environment:

OS: OSX
Browser: Chrome Version 75.0.3770.100 (Official Build) (64-bit)
Library Version: 1.3.0, also on demo page - https://rubenspgcavalcante.github.io/leaflet-ant-path/

I'm going to open a PR:

yes
no

Description:
When zooming out to <= 0 the animation freezes.
Zooming back to >0 the animation unfreezes.

Zoom <= 0 is useful especially when using an ImageOverlay map together with CRS.Simple coordinates.

Looks like animationDuration becomes negative or results in divide/0 as zoomLevel decreases.
I don't have time for a PR now, but if you wrap zoomLevel like this it should fix:
const zoomLevel = Math.max(4, _map.getZoom());

           const zoomLevel = _map.getZoom(); 
        
           const animatedPolyElements = document.getElementsByClassName(_animatedPathId); 
        
           //Get the animation duration (in seconds) based on the given delay and the current zoom level 
        
           const animationDuration = 1 + options.delay / 3 / zoomLevel + "s";

	const zoomLevel = _map.getZoom();
	const animatedPolyElements = document.getElementsByClassName(_animatedPathId);

	//Get the animation duration (in seconds) based on the given delay and the current zoom level
	const animationDuration = 1 + options.delay / 3 / zoomLevel + "s";
