WEB CHATGTPT NOT FUNCTIONING PROPERLY: JSON Array format

Hi, I pay the monthly fee to use advance functions but there are many days that it doesn’t function. When I put a prompt the system is stuck and when I refresh the browser it appears a new conversation with the prompt not solved, only saying: (I give an example)
" Output 1 search query as JSON Array format without additional number, context, explanation, or extra wording, site information, just 1 text search query as JSON Array format.

{ “search_query”: “What is the English term for the commission charged by currency exchange stores for converting euros to yen?” }.
