The directory D:/code/python/serious-python/src/serious_python/example/flet_example/build/windows/x64/python/ is not exists on my system.

I tried to download Python310.zip and extracted to src/serious_python/example/flet_example/build/windows/x64/python manually, then it build successfully.

It's working when I tried to execute flutter clean then flutter build windows.

Maybe the previous flutter build apk affected the subsequent process.
