Issues Opening Spyder via Anaconda

Question

I was forced into some software updates on my laptop (ThinkPad) and after the update when I tried to open Spyder (via Anaconda) and it won't open. I don't have any experience in errors like this or fixing this stuff (and I am aware this may be something that is super simple). Please help. This is the application launch error I am getting:

Traceback (most recent call last):

Please open the Anaconda Prompt and run there `spyder --reset`. Then start Spyder again. That should fix your problem. — Carlos Cordoba, Dec 18 '20 at 01:51
where in the Anaconda prompt is that. I found the restart option but its only for the whole program, I can't find how to reset an application with in Anaconda — Rachel Cyr, Dec 18 '20 at 03:24
You need to type that command and then hit `Enter` to run it. — Carlos Cordoba, Dec 18 '20 at 03:35

Did you try to run spyder on the terminal? It should be prebuild in Anaconda.

Your Spyder config file should contain but is missing 'custom-1/background' in section: 'appearance'. If you have no experience, the easiest thing for you to do is uninstall and install Spyder (via Anaconda). Your other option is to find the config file called in line 513 of C:\Users\cyrra\anaconda3\lib\site-packages\spyder\config\user.py". Then open the config file (if it exists) and correct it. If the file is not found, search for that config file and place it in the expected location.

So I tried the uninstall/re-install and now luck. How would I correct the config file? @cadvena — Rachel Cyr, Dec 18 '20 at 03:29
