anaconda - Spyder 5 ModuleNotFoundError

Question

I have just updated my spyder4 to spyder5 as:

conda update spyder

as I try to launch spyder it gives an Error : No module named 'qdarkstyle.colorsystem'

Here is the complete information :

Traceback (most recent call last):

    sys.exit(main())

I would appreciate any comments on it.

Met with similar problem. I reverted back to previous version till the devs sort the problem out.

conda install spyder=4.2.5
