it is no longer generating the articles

hello good afternoon. I did the step by step to generate the article, it appeared that it was generating at the top of the screen, then the message disappeared and this screen is blank, after updating to the new version of the panel, it does not generate the article. In addition, I learned that the button to copy the HTML, which was extremely useful for publishing on sites with wordpress, disappeared, the writing was copied perfectly, different from copying directly.
