I am building a Flet APK on my Windows machine with the following command:
flet build apk --include-packages flet_audio -vv

I get the following error:

Hi,

I tried again today with Flet version 0.23.0.dev2931 and I got the same error, but this time it occurred at a further step with the package oauthlib:

Error: FormatException: Missing extension byte (at offset 7262)
