Segmentation Fault

Hi
I have re-installed LIGGGHTS-flexible fibers version (https://github.com/schrummy14/LIGGGHTS_Flexible_Fibers.git) on my win10 pc using Ubuntu app. After compilation I am able to run the tutorial examples, however, when I try to run model for my problem, I get the following error.
Strange thing is that I was able to run the same code before. Also, my PC has 12 cores but I am not able to allocate more than 5 cores for the run. All the above problems were not there previously.

Requesting to please help

Thanks
Shubham
