I'm on MacOS 12.2.1. I didn't do anything unusual. I just set a batch to run 5 chunks, set my Mac to not sleep for 2 hours (because Metashape isn't telling MacOS not to sleep during processing, so my Mac sleeps otherwise). I left the room, went to bed, and in the morning it was done and I saw that message.
I'm on a new MacBook Pro with the M1 Max chip. It has never shown me this message before.
