Segmentation fault (core dumped) occurs due to unknown reasons

Thank you very much for providing such a useful tool！ I used simulated diploid potato data and ran classpro. I don't know why the program reported an error. I used two potato haplotypes, the first 5M genome of chromosome 1, and simulated 60×hifi data. Then I used the following code:

FastK -v -k40 -t46 -p potato_5M_2haps.fq 2>&1 |tee log_fastk


$ "/home/jialusoftware/ClassPro/bin/ClassPro"  -v potato_5M_2haps
Info about inputs:
    # of sequence files   = 1
    First (path,root,ext) = (., potato_5M_2haps, .fq)
    FASTK outputs' root   = ./potato_5M_2haps
    Output .class file    = ./potato_5M_2haps.class
    Temp dir path         = /home/work//hapmer_5M_2haps/
    Total # of reads      = 16342
    # of reads per thread = 4086
Global histogram inspection:
    Tallest peak count    = 26 (# of k-mers = 9666852)
    Estimated (H,D) cov   = (26,52)
    Estimated R-threshold = 88

Segmentation fault (core dumped)

I can see that there are some *.class.*files, but when I run it with the simulation data of E. coli before, there is no error, and finally a *.class file is output. I don't know why this is. Please help me share it. Looking forward to your reply!
