I am getting hacked but also am not getting hacked

I am quite scared someone has taken control of my account. I use it alone, no one else uses it, only me. But, for some reason, it keeps doing the one message at a time error.

After this concern for some time, I decided to change my OpenAI API key.
I didn’t program ANYTHING in that 1 day with the new key which had the new key in it. I didn’t even update my old API programs.

But it still happens!
I found that this occurs whenever I stop it from generating.
In my logic, I am pretty sure this occurs because the UI says ChatGPT has stopped generating, but it is still generating.
Please fix this.
