H-a-alpha planes classifier: segmentation fault (core dumped)


I am trying to do H-alpha classification but I am having problems. I am using polSARpro 6.0.3 which is installed on an Ubuntu 20.4.2 virtual machine. When I type the following commands on the terminal:
/polsarpro_v6.0.3/Soft/bin/data_process_sngl/h_a_alpha_planes_classifier.exe -id . -od . -ofr 0 -ofc 0 -fnr 61296 -fnc 1789 -hal 1 -han 0 -anal 0 -clm /polsarpro_v6.0.3/ColorMap/Planes_H_A_Alpha_ColorMap9.pal
I get the following message:
Segmentation fault (core dumped).
Can someone help me to fix the problem?
