alfisya Okay I will try the one from Software Center and just make sure I will try this with a reinstallation of Solus Budgie. Now with a fresh system I still can't launch pipx but the error message has changed to this:
$ which pipx
/usr/bin/pipx
$ pipx --help
Traceback (most recent call last):
File "/usr/bin/pipx", line 5, in <module>
from pipx.main import cli
File "/usr/lib/python3.12/site-packages/pipx/main.py", line 19, in <module>
import platformdirs
ModuleNotFoundError: No module named 'platformdirs'
