Consecutive blunders by GMs

Hey everyone,

I'm looking for one or more examples of games between elite players where one makes a mistake or blunder, and their opponent fails to punish it, blundering the advantage away on the next move. Can anyone help me?

Thanks.

Move 64

Here is one game - lichess.org/V1xQ7Zhr

Praggnanandhaa misses a win on move 8, picking up at least a rook for bishop.

Great thanks, two interesting examples.
