Wrong GPT Generation - GPT-4o

I’ve used the GPT to get answers to questions based on a PDF. The file contains information in Green Building Technologies. The questions asked were also related to that subject. Yet, the answer generation is completely irrelevant to context.

It provided something related to “PolyJuice”.
I’m attaching screenshots related to this issue. Kindly notice.

Also this is a new chat window. I did not ask for any generation prior to this prompt.
