Unable to run with loam horizon data

[777learn]

Hi, i got the data of loam horizon from your own repo i.e 2020_open_road.bag from https://github.com/Livox-SDK/livox_horizon_loam

However i keep getting, [ScanRegistration-1] process has died and correspondingly a blank screen in RViz.

I have read other threads, but i already have Eigen version 3.3.7 and pcl version -> 1.10.0+dfsg-5ubuntu1.
I am using Ubuntu 20.04 but i meet dependency for the modules used (Eigen, pcl etc.)

Please tell me what suitable changes should i make. And where could i be possibly going wrong?
