I can confirm the script still works but may need an update so that it will load automatically, here is the workaround. In order to get it to work I did the following: Start a chat in characterAI then disable the script in tampermonkey. Then hit reload on the chat page. Next enable the script again in tampermonkey. You will know it works when you see a blue button on the upper left side of the chat page that says "Take a Screenshot." and a blue button that says HYW in the upper right.

Work on the script is stopped because I am preparing for exams.

Have you tried refreshing the chat page when the script is on? It may be easier than disabling the script every time and it works for me.
