ModuleNotFoundError: No module named 'backports'

[Siam-Rayhan1]

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'
