reinstall flet==0.25.0.dev3721 and then run flet run main.py -r worked for me.

I've already tried it with a clean install and it doesn't work with -d -r on recursive directories, it only works with files in the main directory.

which python version are you using and did this same happen with other flet stable versions? If no then flet-pre-release might have some flaws.

There have been issues with this for at least 2 stable versions of flet.

There have been issues with this for at least 2 stable versions of flet.

There has to be something wrong with flet integration on some specific os. You should raise an issue regarding this as you said this same happens for stable versions too.

I have these issues with stable version 0.24.1, and also with the 0.25.0.dev3721 version. flet run work fine, flet run -d or flet run -d -r or flet run -r keep hanging. Very anoying while developing.
