Kernal in Jupyter Notebook Dies Since I Modified Paths

Jupyter notebook was working fine for me just yesterday.I use a Windows system, and I just edited my environmental variables for using PSCP. After I added pscp as a path, my jupyter notebook kernel started dying every time I open it. I looked online for solutions and found that I should re-install all the python packages. I tried doing that, but I got the same error. I also tried running 'conda clean -tipsy', but that did not fix the error either.

When I run 'jupyter kernelspec list' I get:

C:\Users\username>jupyter kernelspec listC:\Users\username\Anaconda3\lib\site-packages\jupyter_client\kernelspec.py:159: UserWarning: get_ipython_dir has moved to the IPython.paths module since IPython 4.0.  dirs.append(os.path.join(get_ipython_dir(), 'kernels'))Available kernels:  python3    C:\Users\username\Anaconda3\share\jupyter\kernels\python3

When I messed with system paths, I just edited and added more paths, but I am guessing I did something to the jupyter notebook path because it was working fine before I made the other path edits.

I attached a picture of my paths (username blacked out) since I can't include it as a text error. path error. The last 2 paths were just added - the first one for pscp, the other to try and fix my jupyter notebook path error (which didn't work).

Here's my error while opening jupyter notebook:
