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 error usually appears because you installed pyqt5 with pip at some point. Now you have to uninstall Anaconda and reinstall it following the instructions in our video to be able to successfully run Spyder again. Please try that and let us know if it works for you.
On macOS, the first time you open Spyder, you may see a message that it cannot be opened because the developer cannot be verified. If so, right-click on the application, select Open, then click Open in the resulting dialog, and the warning will no longer be shown.
From the command line: Type spyder in your terminal (or Anaconda prompt on Windows). From Anaconda Navigator: Scroll to Spyder under Home, and click Launch.
Restart your machine, in case the problem lies with a lingering process or another such issue. From the Anaconda Prompt/Terminal/command line (on Windows/Mac/Linux), run the command spyder --reset , which will restore Spyder's config files to their defaults, which solves a huge variety of Spyder issues.
Just try this :
conda uninstall pyqt
conda uninstall sip
conda install sip
conda install pyqt
conda upgrade spyder
this worked for me.
