Describe the bug

After updating to flet 0.25, the Linux executable (result of flet build linux) stopped working. When started, the process starts (the application "runs"), but nothing happens, neither a window opens nor an error is displayed.

flet run on the other hand works just fine.

Code sample

Code

main.py

import flet as ft

def main(page: ft.Page):
        page.title = "Test"
        page.update()


ft.app(main)

To reproduce

1. Build with flet build linux
2. Run the returned executable
3. (optional) wait a long time

Expected behavior

A empty window opening or an error displaying.

What Python dependencies does the app have?

[mfxbe]

None but flet itself. I tried it with a completely new and empty project.

On Windows 10 or 11, it happens a bit different. A blank screen opens and nothing else happens. It doesn't give me any errors, the screen just stays blank. At my computer, it's not always, though, which makes it even weirder. Thinking about posting an issue, but need to make more troubleshooting first.

Not built version is working fine.

I have the same problem, in Linux it doesn't open or do anything, and in Windows it's a white screen without errors.
