[D] Why would such a simple sentence break an LLM?

This is a prompt I entered into MS Copilot (GPT4 Turbo).

It's in german but it just means "***Would there be any disadvantages if I took the full bath first?***"), so this can't be another SolidGoldMagikarp or similar, because the words clearly were in both tokenizer and training vocab.

Why would such a simple sentence cause this? Any guesses? (also tried with Claude Opus and LLama 3 70b, which worked fine)
