ModuleNotFoundError: No module named 'backports'

Question

Basically I'm making an app using Pythons kivy and kivymd frame work.In my app I'm using instaloader module.Using Github Action (CI) I'm converting my app to apk. After converting,when i try to open my apk it crashes immediately.

Here's my Debug Log

I/python ( 8065): Traceback (most recent call last):

Here's my buildozer.spec requirements.

requirements = python3==3.9.10,hostpython3==3.9.10,kivy==2.1.0,pillow,kivymd==1.1.1,certifi,android,instaloader==4.10.1,plyer==2.1.0

Then i solved this issue following this

 Before modification 
from _lzma import * 
from _lzma import _encode_filter_properties, _decode_filter_properties 

After modification 
try: 
 from _lzma import * 
 from _lzma import _encode_filter_properties, _decode_filter_properties 
except ImportError: 
 from backports.lzma import * 
 from backports.lzma import _encode_filter_properties, _decode_filter_properties

And it works.But now getting another error and that is

I/python  ( 7917):    File "/github/workspace/.buildozer/android/app/lzma.py", line 31, in <module>
I/python  ( 7917):  ModuleNotFoundError: No module named 'backports'
