Open broadcast studio video not saved?

I just filmed a very elaborate video with open broadcast from my desktop but accidentally put the laptop into 'sleep mode' before I finished recording (I don't know exactly what the condition is)

The video is no longer saved, is there any way to save it?

If it is not saved, you can't save it either, as the recording, as you said, does not exist.

You can only save something if you e.g. Deleted a file & then retrieved it from the trash, but here the recording was easily canceled and is therefore not available.
