Short description of error
Suddenly, I don't know when, I only realized it when i was trying to render, the render engine changed to cycles.
I have no clue how this could happen, but when trying to change the engine back to cycles, it didn't show up in the dropdown menu.
Then I decided to change the engine manually via blender console command. The error message said me, that cycles isn't in the render engine enum.
After restarting blender everything worked well.

We need steps to reproduce this problem, otherwise there isn't much we can do.

Probably some Python error caused issues for the Cycles add-on, but it's hard to guess what caused this. Could also be another add-on.
