If I want to check the logs, where should I look? Also, could you please provide the terminal results of successful execution so that I can know whether my execution is successful or not.

You may follow the tutorial from Free5GC: https://free5gc.org/blog/20240110/20240110/

Your issue on the other thread, heavily remind me of an outdated gtp5g module. Make sure to remove the previous module; modprobe -r gtp5g, and compile/install/modprobe the new module.
If you are also using Free5GC's UPF, you must it to the very latest version for everything to work.

Cheers,
Valentin
