jupyter kernelspec list
Available kernels:
python3 C:\Users\Ashwin\AppData\Roaming\jupyter\kernels\python3

this is being displayed when i did: "jupyter kernelspec list" on the anaconda prompt

Hi @Ashwin-gx - this is a duplicate of several issues. I would first recommend upgrading your jupyter_client package, which should also update your jupyter_core package (where the secure_write() method now lives). Once you upgrade, restart the notebook server and reattempt the kernel startup. I suspect you'll probably have the same issue, but the error message should resemble that described in #5197. To get around this issue, take a look at this comment - which provides a couple of work arounds: #5197 (comment)
