I don´t know if this error was caused maybe because I deleted one environment from my anaconda navigator, but every time I try starting jupyter lab (from various environments in anaconda or from the default python installed on my computer) I get this error with every single notebook:
Error Starting Kernel: '_xsrf' argument missing from POST
I have tried setting the following configuration to True:
c.NotebookApp.disable_check_xsrf = True
By generating the jupyter_notebook_config.py file from Pycharm. I also deleted the .jupyter folder but nothing of what I have done works.
