This is the error that shows up everytime. I tried reinstalling jupyter as well but nothing worked. Is there a way I can use jupyter without having to install anaconda?

I want to use Jupyter-matlab notebooks. I've downloaded Anaconda navigator and followed the steps from this web: http://jmlilly.net/jupyter-matlab Unfortunately, when I try to open a matlab notebook there is a kernel error.
I've been trying re-install anaconda, jupyter, matlab-kernel, change environment python version (2.7, 3.7, 3.8, 3.9) etc. but it doesn't work. Matlab version: R2021b and R2022a (tried both).
Full error traceback from jupyter:

I had the same problem. This post helped me to solve it. For some reason, the matlab kernel config file points to the wrong python location.
Solution
Edit the file %APPDATA%\jupyter\kernels\matlab\kernel.json so that the first argument points to the correct python executable. In my case from:
{"argv": ["/tmp/conda_envs/258853ccd52b78b326300497/bin/python", "-m", "matlab_kernel", ...
to
{"argv": ["C:\\Users\\YOURUSERNAME\\.conda\\envs\\ENVNAME\\python.exe", "-m", "matlab_kernel", ...
Or whatever is the correct python path to your environment (change YOURUSERNAME and ENVNAME). In windows you can find it using where python
Extra info
For debugging and finding the kernel.json file, I used
jupyter console --kernel matlab --debug
I tried installing google-colab and now jupyter notebook won't work, neither will anaconda navigator. Only way I can open jupyter notebook is via cmd but then the kernal error I get means I can't run anything
