I had the same problem which was mainly due to an update to PyQt5, the following code helped me.

Run cmd.exe as admin:

conda update conda
conda update anaconda-navigator

reinstall PyQt5:

pip uninstall PyQt5
pip install PyQt5
pip install pyqtwebengine

I was working on my Windows 10 machine and I m not sure which package  broke  Spyder and Anaconda Navigator  but could have been either  or  or both Kivy-1 10 1 and moviepy-0 2 3 5 which gave me problems  I installed with either pip or conda  So of course I looked on this site to see what to do to fix   I found how pyqt was probably the issue   I uninstalled pyqt  kivy  and moviepy by using  pip uninstall     I found where or how they were installed by  pip list  and  conda list     After they were uninstalled I used  conda install - c anaconda pyqt  to reinstall pyqt   After installing pyqt I launched Spyder with no problems

I tried the following  janny loco s answer first and then reset anaconda to get it to work   Step 1    activate root conda update -n root conda conda update --all   Step 2   anaconda-navigator --reset  After running the update commands in step 1 and not seeing any success  I reset anaconda by running the command above based on what I found here   I am not sure if it was the combination of updating conda and reseting the navigator or just one of the two  So  please try accordingly

You need to run the cmd prompt from the Scripts directory of Anaconda where ever you have the Anaconda parent folder installed   I happen to have in the root directory of the C drive on my Windows machine   If you are not familiar there are two ways to do that   A  Use the key combination Win-key   R then type cmd and hit return to launch the terminal window and then type  cd C  Anaconda Scripts  or whatever directory path yours is   B  Navigate using windows explorer to that Scripts directory then type cmd in the address bar of that window and hit return  that will launch the terminal already set to that directory    Next type the follow commands waiting in between for each to complete   activate root conda update -n root conda conda update --all   When complete type the following and Navigator hopefully should launch   anaconda-navigator

You need to update Anaconda using   conda update   and  conda update anaconda-navigator   Try these commands on anaconda prompt and then try to launch navigator from the prompt itself using following command   anaconda-navigator   If still the problem doesn t get solved  share the anaconda prompt logs here if they have any errors

I struggled with this problem for a couple of hours  got the same error message you showed in your attachment   I knew the problem had to do with the path variable  specifically the PYTHONHOME variable    I finally found I had set the PYTHONHOME path to the python exe file  C  Anaconda3 python exe   It should be set to the Anaconda folder that contains the python exe file  C  Anaconda3     After that I could run the Anaconda Navigator
