What has happened? How can I prevent this in the future?
Welcome @user65526! So, generally speaking, more information is needed for something like this. The closest I can guess is: some kernel extension, possible related to a graphics card or external video display (?) is getting hung up with Apple's "Power Nap" feature, also known as darkwake[s]. I'd recommended disabling the feature entirely, by entering in your terminal:
sudo pmset -a darkwakes 0
This will disable "Power Nap" in all cases. IMO its not a particularly useful feature anyway.
My guess, in my case it happened because I simultaneously closed laptop and plugged off external HDMI display. I think I should first detach laptop from external devices, let handle it and then close laptop.
Report from my case:
