Segmentation fault (core dumped) when trying to start conda-installed spyder 3.2.8

Developer Note: *This issue is now resolved in Spyder >=3.3.0. Therefore, to fix the problem, just run conda update spyder from the command line (Anaconda Prompt if on Windows) to get the latest version, or pip install -U spyder if you don’t have Anaconda.

If this doesn’t work, then you are experiencing a different issue; try conda install pyqt=5.9 and conda install pyqt=5.6 to see if it fixes it.*

I’ve gone through the troubleshooting document and have tried the various suggestions within including uninstalling and reinstalling through conda. I haven’t tried installing via source, I’m hoping there is something else going on that won’t require that.

Update: aaaaaand ten minutes later it’s working. I did absolutely nothing different since posting this question, I could not tell you what changed.

@addyblue Try conda install pyopengl

@Samarth-Tripathi3, this should be solved by doing

conda install pyopengl

EDIT: Now that Spyder >= 3.3.0 is released with the built-in fix for this, the current solution that should fix this is now just conda update spyder.
