jupyter notebook keeps reconnecting - python

I'm getting error while connecting the jupyter notebook. It says connecting to the kernel. I'm not able to execute any of the queries in that. Could anyone help me out with this.
Below is the error message and logs in anaconda prompt.

If you are using jupyter behind a nginx proxy, this post may be effective.
Add this line to nginx conf.

"Invalid credentials" when running `jupyter notebook --no-browser` from remote server

I tried everything here and nothing worked:
Jupyter Notebook Server password invalid
How to disable password request for a Jupyter notebook session?
When I generate a password it doesn't give me a token but when I type in the password it doesn't work. When I copy and paste my token, it also doesn't work.

Jupyter Notebook kernel restarts every time I import pixiedust

Running one line of code "import pixiedust" makes the kernel die and automatically restart every time I try it. I'm using Jupyter Notebook via Anaconda in MacOS BigSur 11.2.3.
import pixiedust
this is my only line of code, the rest of my code works fine (the part not using pixiedust).
that's the terminal output:

Jupyter notebook not launching from navigator or command prompt

I'm using Anaconda. I cannot get jupyter notebooks to launch from either the navigator or the command prompt. I'm working from windows 10. I've tried jupyter notebook --debug and get the following results.

seems like its getting hung up somehow or not finding the files it needs. I've tried uninstalling anaconda and reinstalling and I'm having the same issues. Any suggestions to get jupyter notebooks working would be much appreciated.
Edit: I've gone to localhost:8888 and nothing is there.

What I did:
apt-get install docker*

it said [C 19:38:32.851 NotebookApp] Running as root is not recommended. Use --allow-root to bypass.
I runned docker run -it --rm -p 8888:8888 4fdcd3a6ff59 /usr/bin/jupyter notebook --allow-root, everything in docker is okay

Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
http://localhost:8888/?token=89a3809bd589557e08e31d7fbd475e6e17bb333fe2311745
but I have no access neither using browser on local device nor using http://ip:8888/ in local network
What I should do to make it work?
Try binding docker to all interfaces.
-p 0.0.0.0:8888:8888

It will cause more error later. How can I fix it?

Thanks to #Petesh, I can use ipython notebook temperately now, using the command below:
ipython notebook --ip=127.0.0.1
And for further solution, I found that in my Mac's "/etc/hosts", 127.0.0.1 is not set to localhost. That's the final solution.
