Chatgpt4o can't identify Chinese characters in the picture

I don’t know if it is because the new version of chatgpt came out, but somehow 4o can’t really extract text with Chinese characters in the picture now. Usually to finish my job I need 4o to help me extract the characters and give me English translation at the same time. These two days when I ask 4o to generate characters in the picture, the contents generated is not related to the content in the picture at all. Please help me figure out this issue.
