- Jupyter Notebook is not installed: If Jupyter Notebook is not installed in your Anaconda environment, Anaconda Navigator will not be able to launch it.
- There is an issue with the environment: If there is an issue with your Anaconda environment, Jupyter Notebook may not launch from Anaconda Navigator.
- There is an issue with the configuration: If there is an issue with the configuration of Anaconda Navigator, it may not be able to launch Jupyter Notebook.

Jupyter notebook not launching from Anaconda Navigator
I had the same issue on my computer. The issue was that a particular file went missing while updating the notebook. Please check the following file in the folder: /Users/your-name/.anaconda/navigator/scripts/notebook.sh and the corresponding output and error files called something like *out.txt and *err.txt The script notebook.sh should look like this:
The error message said that the file jupyter_mac.command did not exist. This was why the notebook was not getting launched.
To fix it simply create this file, jupyter_mac.command , in the /Users/your-name/anaconda3/bin/ folder. The file is the following simple script :
After saving this file, you may need to give it executable permission using the chmod +x command.
