Hi. Problem with harfbuzz. Buildozer 1.5, NDK 26b

[RadoslawGlebicki]

Hi. This is my first post here. I am fighting with Buildozer a lot of time. Different versions of everything.
Now I think everything is the newest.
Versions:

Python: 3.8 in Fedora 30
Kivy for project: 2.1.0

OS: fedora 39 server in VM qemu
Kivy: 2.3.0
Cython: 3.0.8
Pyjnius: 1.6.1
Buildozer: 1.5
harfbuzz: 8.2.1
NDK: 26b
java: java-17-openjdk-17.0.9.0.9

Description
With NDK 25b can't compile libffi because clang doesn't work. Lower NDK now is not accepted by buildozer.

Actual error with NDK 26b:

Try downgrading Cython below 3.0.0. Last time I looked, it wasn't supported.

Explanation what helps:
back to NDK 25b
and remove rpms: Pyjnius and Cython (stayed those from pip)
