My apk inside ubuntu using buildozer, but getting error `'clang' failed with exit code 1` for ndk

This is the error I am getting error:

command '/home/francois/android-ndk-r25b/toolchains/llvm/prebuilt/linux-x86_64/bin/clang' failed with exit code 1. 

I changed from r23 to 25 and also changed my Cython version. I also installed r25b manually. These are the requirements inside my .spec file

requirements = python3==3.10.12,kivy==2.2.1,sdl2,plyer==2.1.0, requests,cython==0.29.36android.ndk = 25b, android.ndk_path = /home/francois/android-ndk-r25bandroid.api = 28, android.minapi = 21, android.archs = arm64-v8a
