Executable Built with auto-py-to-exe Fails with Flet v0.25.1 (Downgrading to v0.24.1 Resolves Issue)

[manjeetparjapati]

When packaging a Python application using the Flet library with auto-py-to-exe, the resulting .exe file fails to launch and throws an HTTP Error 404: Not Found. This issue occurs with Flet version 0.25.1. However, downgrading to Flet version 0.24.1 allows the executable to run correctly without errors.

Environment Setup:

Operating System: Windows 11
Python Version: 3.12.2
Flet Version: 0.25.1
auto-py-to-exe Version: 2.45.0
