[Python] Pyang can't display subtree when using "-f tree"

Good afternoon and Happy Friday!

I installed Pyang in a venv environment in Ubuntu 24.04.1, and for the life of me, can't get it to display a subtree of a Yang model.

All it does is just goes to another prompt, with verbose it just shows its reading.

Please see below:

(.yangenv) administrator@administrator-VMware-Virtual-Platform:~/Documents/yang/vendor/cisco/xe/1791$ pyang -f tree Cisco-IOS-XE-interfaces.yang
(.yangenv) administrator@administrator-VMware-Virtual-Platform:~/Documents/yang/vendor/cisco/xe/1791$ pyang -f tree -verbose Cisco-IOS-XE-interfaces.yang
pyang 2.7.1
(.yangenv) administrator@administrator-VMware-Virtual-Platform:~/Documents/yang/vendor/cisco/xe/1791$ pyang -f tree --verbose Cisco-IOS-XE-interfaces.yang
