Troubleshooting Godot Script: Android vs. Windows

Hey everyone, I'm encountering an issue with a Godot script that behaves differently on Android compared to
Windows. Here's the script in question:

var file = FileAccess.open("res://icon.png", FileAccess.READ)
var path = file.get_path_absolute()
print(path)

The script is intended to open a file ("icon.png") and print its absolute path. Surprisingly, it works as expected on Windows but fails on Android. I'm puzzled by this discrepancy and would appreciate any insights or potential solutions to make it work consistently across both platforms.
I want this because I need to pass the absolute path to my Custom Modules in C++.
Thank you in advance for your help!
