ChatGPT stopped producing graphs?

I've been using ChatGPT for years and most of what I do is generating content for Economics discussions so I do a lot of things that result in ChatGPT producing graphs.

I recently got an offer for a free month of ChatGPT Plus so signed up but around the same time it started failing to produce graphs. Instead, it'll offer to give me input I can plus into Desmos which can work in a pinch but why is it suddenly no longer working? I've closed out my tabs and reopened them, I've asked for prompts again, but it's not working.

Some of what it has said to me (meanwhile if I google the situation, it says the graphing utility is not down):

• It seems like I can’t do more advanced data analysis right now. Please try again later. Once I can run Python again, I’ll generate the full, labeled graph you requested
  *It looks like my chart generator temporarily went offline — but no worries, I can retry it as soon as it’s available. Here’s what the side-by-side graph will show once rendered:
• The plotting kernel is still not responding
• It looks like the graph generation is still failing on my end — probably a temporary issue with the plotting environment.
• It looks like the plotting tool failed before producing the step-by-step competitive-market graphs.
• The graphing tool still isn’t rendering
• If the plotting tool comes back online soon, I can graph side-by-side short-run diagrams
• The plotting kernel is still unavailable. If you’d like, I can regenerate this plot as soon as the Python graphing environment is back up.
• So even though you’re using ChatGPT Plus, which gives access to GPT-5 and advanced reasoning, the interactive Python/graphing environment can occasionally fail to start. It usually comes back automatically later the same day (no action required).
• The plotting tool is still unavailable
• Thought for 7s It looks like I can’t run the plotting tool right now — sorry about that.
• Okay, so the plotting sandbox is still being grumpy 😅 — but we don’t have to stop. I’ll give you the exact Desmos version of the graph we’ve been trying to render. If you paste this into Desmos, you’ll get the two pictures we’ve been talking about: one for a monopoly (with profit) and one for monopolistic competition in the long run (tangency, zero profit). You can do them in two separate Desmos tabs.

And don't even get me started on my "can you find a quote from an economist that supports this"

• "Sure, here it is"
• "great, where is that from"
• "Samuelson 1948"
• "Great, what page?"
• "Page 254"
• "I have that page, it's not there"
• "Oh, I paraphrased"
• "Great, give me all sources you paraphrased from"
• :: gives them to me ::
• "Ya, those don't say that"
• "Great catch, you're right to double-check. From here"
• "those quotes don't exist"
• AHHHHHHHHHHHHH
