It was working good yesterday, but today I don't know why I get this error as I'm new to Python at all


Absolutely! Try conda uninstall jupyter notebook in the CLI and then install it again using conda install jupyter

What is this kernal error when I make a python 3 jupyter notebook?

I just installed miniconda,jupyter notebook, python, and some packages.
I have the appropriate version of pywin32.

I got a similar issue yesterday. Try running this code in the CMD
conda install pywin32
and install it if you use Anaconda.

check out permissions to that folder inside users\DELL\
I always make sure to install the program folder closer to the root c:\anaconda**

is there any solution for kernel error in jupyter notebook(i installed jupyter notebook in mysystem)

Python 3.6 install win32api?

Jupyter Kernel ImportError : DLL load failed: %1 is not a valid Win32 Application

I've tried to follow the solutions proposed by previous questions with a similar issue but to no avail. I've (to the best of my knowledge) uninstall python and anaconda numerous times and reinstalled the 64 bit version (I am running a 64 but OS) but the issue persists. Here is the unhandled error of my kernel.
