Something seems to have gone wrong

Hi im sorry but i dont know what to do I’m experiencing a serious issue with my main OpenAI account. About 4 h before the error started, everything was working normally. Then suddenly, I became unable to send any messages to the assistant. I can type in the message box, but when I press “Send,” I immediately get an error such as: “Hmm… something seems to have gone wrong. This happens everywhere, including: the web version (Chrome), the mobile app, on Wi-Fi and on mobile data, and on different devices. I tested another account on the same devices and network, and that account works normally, which suggests the issue is specific to my main account. I have already tried: clearing cache & cookies, restarting the browser and app, switching networks, reinstalling the mobile app, using a different device. Nothing helped. Did you know how to fix it ? It’s “plus” versionand and I’m honestly afraid that it will stay like this forever
