Bug in models GPT4o-mini and GPT 3.5 turbo

I have an implementation using the OpenAI Assistants API, but my assistant has only been responding in English, regardless of the language I use for my questions. I have been using the Assistants API for 2 or 3 months without any issues, but I noticed this error today. Additionally, when I ask a question about the documentation related to my assistant, it provides incorrect and repetitive information, asking me to ask a question again (even though I am already asking questions, it keeps giving the same response).
This happens with the gpt4o-mini and gpt 3.5 turbo models.
