What was the issue please?
You can push a prerelease so I can give it a try.

[FeodorFitsner]

Racing condition. It occurs with Flutter animations/transitions, like in your case a routing view has been already removed from a page, but routing animation is still happening.

[FeodorFitsner]

You can try the fix with pre-release. It's ready.

Hey! I just tried with the latest pre, and same issue. Requirements.txt: flet==0.5.0.dev1181
https://startup-name-generator.pages.dev/

[FeodorFitsner]

It's still loading 0.4.0, not the latest pre. You should publish it with --pre:

flet publish your-script.py --pre

[ndonkoHenri]

Ah, i forgot that parameter.
Feed-back tomorrow please 😴

[ndonkoHenri]

Hey. It's still not working. Can you check if the flet pre was successfully loaded?

[FeodorFitsner]

If you look at index.html sources you'll see that loading of pre-release packages from PyPI is not enabled (flet publish your-script.py --pre sets it to true):

and it's still loading 0.4.0:

I ran it with the --pre this Time.
No Problem, I will do it once more, and let you know.
