Epinano_Variants.py fails to produce the output

[francesco227]

linux version (HPC): Linux 5.14.0-503.23.2.el9_5.x86_64
python version: Python/3.12.4-GCCcore-13.2.0q

when running Epinano_Variants.py (latest release v1.2) as:
python epinano_variants.py --reference path/ref.fa -b path/my_bam.bam -n 8
no output is produced (no csv files at the end of the analysis), in the log file instead it is found:
"analysis took: 500s to complete" (usually takes at least some minutes)

instead, when running slim_epinano_variants.py (latest release v1.2) as:
python misc/slim_epinano_variants.py --reference path/yeast_rRNA_ref.fa -b path/my_bam.bam -n 8 --type g > my_output.csv
the output file is normally produced
