ModuleNotFoundError: No module named qdarkstyle.colorsystem [Python]

I happened to update my package of spyder to v5 from v4, I got the below error message,

Traceback (most recent call last):
  File "/home/c2c/anaconda3/envs/py37/bin/spyder", line 11, in <module>
    sys.exit(main())

ModuleNotFoundError: No module named 'qdarkstyle.colorsystem'

Solution

It looks like there is some issue that needs a dev fix, the way I was able to get back things to work was reverting back to the previous version of the package spyder,

% conda install spyder=4.2.5
