Probe Basic AttributeError

Hello, I have installed bookworm and probe basic according these guides in this forum:
Py3 -Development Install for Probe Basic and QtPyVCP
Py3 - Probe Basic Config Conversion Doc Lcnc 2.9+

Sadly when I try to start my machine I get the following error message:
See attached .txt
I have already tryed to reinstall QtPyVCP and probe basic but it did not help.

the development version must be run with the supplied launchers as the activate the require virtual environment, they are scripts. if you want to just use probe basic you need to use the .deb installation method as that performs a system wide install that works like any other user interface.
