Ubuntu 24.04.1LTS terminal not launching after rasa installation

Ubuntu 24.04.1 LTS. I tried 3 times reinstall and it happened every time. is that a known problem? Rasa will not install with python 3.12 so I had to downgrade to 3.10 to accommodate the rasa installation. As long as the terminal is open after installing rasa I can use it but once closed it never reopens. Maybe I should change back to python 3.12 after rasa is up and running and before exiting the terminal? is this a known issue?

orry I’m not a coder so I will be plain: here are the steps that did not and did work so far changing back to python312 did work for ubuntu but took out rasa. I had to create virtual environment for Rasa with the python 3.10 version in order for both to work. now my ubuntu has 3.12.xx but my rasa keeps 3.10.xx So far so good here is the command to create a separate environment with python 3.10

python3.10 -m venv rasa_env - maybe that will help someone- it took some research ;-)
