Error while running the process p p > b b~ a a $ h in heft model

Hi,
While running the process p p > b b~ a a $ h in the heft model, I encountered the following error while launching the output:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

And even after this error the program keeps running (for 30+ minutes)
Edit: In the end, the program gives the following error-

INFO: Combining runs
Error when reading /mnt/c/Users/Harshal.Kulkarni/MG5_aMC_v2_9_4/pp_bb~aa$heft/SubProcesses/P1_gg_bbxaa/G28/results.dat
Command "generate_events run_01" interrupted with error:
ValueError : could not convert string to float: ''

Can anyone please tell me the cause of this error and the possible solution?

Thanks,
