问题
I have two environments in which spyder just doesn't want to launch. I click the icon there is a waiting cursor then nothing happens. One of the two is totally new that I just made today. After installing some packaged (pip install pytrends was the last one) it stopped opening.
Note: the general spyder at: C:\ProgramData\Anaconda3\Scripts\spyder.exe does launch, but not the one for the environments.

This solves the problem:
conda upgrade qt

Just try this :
- uninstall pyQt using
conda uninstall pyqt
- uninstall sip package
conda uninstall sip
- then install these packages in following order
conda install sip
conda install pyqt
conda upgrade spyder
this worked for me.

I was not able to launch Spyder and Jupyter notebook from anaconda environment (Mac OS).
Following command worked for me:
conda uninstall tornado
conda install tornado==4.5.3
Just uninstall tornado and reinstall it.

I had faced a similar issue while running spyder from the anaconda navigator or the conda terminal. To overcome this issue you just need to follow some simple steps.
open the anaconda navigator. ( You can also use anaconda prompt and type "anaconda-navigator" at the console)
Open the application and then follow the steps as shown in the image. here we are creating a new environment with a python of version 3.6. I think the 3.7 version is unstable and doesn't work properly. It worked for me, hope for you too !!!
see the image here and follow the steps.
it will take some time to download resources to set up the environment for the first time.
after following the steps launch the application. Make sure to run the environment first to be able to launch the application.

This problem is solved in the newest version of conda. Currently it is on the conda canary channel, you can get it by running conda update conda -c conda-canary

For me the outdated library was spyder.kernel. The best solution is to open a new python environment (just input 'py' in command line to build a new environment) and run the following script and it tells you what library is missing or outdated:
from spyder.app import start
start.main()
