Assist didn't work, all time can't understand

Hi,
I have been trying to use Assist for a long time, but I was only able to use it in the first version of Home Assistant.
I remember having installed the integration with “ChatGPT”, but when installing it, almost everything began to respond to the fact that it could not understand it.
I deleted the “ChatGPT” integration and since then I have not been able to use Assist because I always get the message “Sorry, I did not understand”. I have been waiting for updates to see if it was corrected, but nothing.

I’ve searched the forums a bit but can’t find a solution.

Thank you. Nico
