I tried installing _bz2 module with sudo apt-get install libbz2-dev but still I got the same problem then I followed this sudo cp /usr/lib/python3.8/lib-dynload/_bz2.cpython-38-x86_64-linux-gnu.so /usr/local/lib/python3.8/
&
sudo cp /usr/lib/python3.8/lib-dynload/_bz2.cpython-38-x86_64-linux-gnu.so ~/.pyenv/versions/3.7.10/lib/python3.7
Again I got the same issue. What else I can try ?

Can you try installing the pyenv Python 3.7.10 again after you installed the library?

Thanks @vojtechjelinek it worked for me.
