Not working with error

[izark1]

Hi, I tried it to repack python elf package (built using python 3.9) after extracting it and did some modification on one file, and repacked the content as:
[root@rhel-sp-01 ~]# python3.9 pyipx.py phCodex phCodex_extracted /tmp/phph/phCodex
[*] Asset modified: libexternalcalls.so
[+] Repackaging finished

but when running the new executable I get the following error:
Traceback (most recent call last):
