Fail to debug run_example

Reproduce the VSCode debug flow for run_example after building app.zip, starting with lib\main.dart and the packaged flet\app\main.py shown in the log. Check why the debug runtime cannot load lru._lru even though the archive is shared with release mode. Done means debugging run_example completes and displays PASS without the ModuleNotFoundError.

Hi I tried to run run_example using VSCode, and I package app.zip and build run_example.exe successfully. But when I tried to Debug it, there is a python file name shown in panel instead of PASS. I checked the OUTPUT and DEBUG CONSOLE, I find an error "no module named lru".

Detailed information are as followed:

It really confused me because I think the same app.zip is used in both release and debug mode, it should contain the lru dependency.
I submitted an issue #116 yesterday about that I can't compile the app automatically, I manually moved some files, I don't know if it caused the problem.
