Jupyter Notebook Kernel busy all the time

Question

I have instaled anaconda and python works fine in Sypder , IPython etc . However I am not able to run python notebook.

Kernel gets created , it also connects but it shows the dark circle busy symbol throughout . There is no problem with the firewall or antivirus . I have tried by disabling both .

I am also not able to open python terminal from notebook there is some powershell error.

Can anyone suggest something ?

Edit 1 : Added the snapshot and the log

And the image where kernel is always busy

did you try executing jupyter in a seperate conda environment? — ohlr
@NihalSangeeth its 5.1.0 , I have actually installed anaconda . I also tried 4. versions as welll no help — Dnyanesh Khedekar
Does it happen when you create a new notebook/ When you open an already existing notebook or both the times? Also is there a ipynb_checkpoints folder created when you open the notebook in a new directory? — anand_v.singh

I was also getting the same issue, I tried a lot of different stuff but nothing seemed to help me out. Ultimately, a Kernel Restart instead of Kernel Interrupt helped me out! The kernel restarted and I was able to run the kernels as usual.

I think this is just a workaround if someone finds the real solution please do let us know!
