Any recent examples of strong programs losing with white at longer time controls?

Are there are any games to check out? It would be fun to go through them to see what happened. Of course, it shouldn't be a purposefully bad opening.

There are quite a few examples from correspondence games and computer-computer play. Just one for example:

It would be very interesting to know the TC for this game, and where each engine left the book!

SSDF time control is 40 moves/2 hours followed by 20 moves/each following hour. They generally use the engine's own book, if it has one, but I am not clear what they do for engines like Stockfish that have no official book.
