I am experiencing an issue where I am unable to launch Jupyter Notebook from the Anaconda Navigator. Despite multiple attempts, the Jupyter Notebook does not start. I have tried restarting the Anaconda Navigator and my computer, but the problem persists. Any assistance in resolving this issue would be greatly appreciated.
Because I’m a new user and my account is restricted by anaconda community, so I cannot upload more than one pic!
uninstall anaconda and reinstall. Use the ‘only for me’ option. That fixed it for me.

I also have the same problem, but it gives me the text underneath that I can copy that may contain the error? It is:
