When I launch Jupyter Notebook from Anaconda, a web page opens and gives me the below error message

And it will automatically check the first folder.How should I solve this problem?I downloaded Anaconda again, but the problem still persists.

When I try to open Jupyter it appears this message:

I’m having some issues with opening Jupyter. I just installed Anaconda, but got an error when I try to write “Jupyter notebook” in terminal.

I am beginner and have installed Anaconda3.For the purpose of learning Data Science . In my old laptop I have successfully installed and run it in default browser. But now I’m using Windows 11, I’m having trouble in accessing the jupyter-notebook from anaconda navigator. I had uninstalled and install many times but it’s opening the notepad with the html code[named : jpsever]. I also run the html code but it displays that “can’t reach this page. localhost refused to connect”.

I have downloaded Anaconda on my work station, and CTRL-Y, which was the Redo shortcut, is no longer working. Instead, I could have to use CTRL-SHIFT-Z.

i was trying to do my lab exercise but there is error but i dont know whats the problem and where show i fix it. can anyone show me whats the problem so i can fix it? this is the code:

when launching Jupyter Notebook from Anaconda, I get the following Error:

After installing Anaconda, I want to open the jupyter notebook, but I can’t open it when I click it directly, and I get an error with a command line statement, which is very confusing. I’ve re-uninstalled ananconda and reinstalled several times and it’s all like this.
