There’s multiple ones, more prevalent with the use of ai. Like translating the ‘render’ that is an computer generated image in the meaning of plaster work.

But before that I remember a Dragonball Z episode where Gohan says to Krillin ‘lets amscray’ being pig Latin for ‘scram’, was translated like ‘to amscray’ was a verb in the DBZ universe. That’s not a big mistake, but still it stuck with me long enough to be the first example to this thread’s question.
