PermissionError while starting the kernel in Spyder's IPython console

When I launch spyder, this error appears :

Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\lib\site‑packages\spyder\plugins\ipythonconsole.py", line 1572, in create_kernel_manager_and_kernel_client
kernel_manager.start_kernel(stderr=stderr_handle)

PermissionError: [Errno 13] Permission denied: 'C:\\Users\\Sébastien\\AppData\\Roaming\\jupyter\\runtime\\kernel‑e1f2b044843b.json'

I am not experienced at all in programming but I tried to enter commands in the Anaconda prompt but none of this worked ("conda update jupyter_client" and "conda update --all") I also tried to install and uninstall but I still get the same error.

What did help for me was to allow insecure writes:

yourPythonPath\scripts\activate.bat
set JUPYTER_ALLOW_INSECURE_WRITES=1
spyder

Alternatively you could also set JUPYTER_ALLOW_INSECURE_WRITES to 1 in your global Windows environment variables.

This seems a permissions issue. Running Spyder as administrator (right click on it-> run as administrator) solves the problem.

UPDATE: As per @CarlosCordoba: "To fix this the OP needs to run conda update anaconda and then conda update jupyter_client in the Anaconda Prompt"

Note that the original workaround worked as well in this case.
