The vapi assistant doesn't work for me anymore. It says the first response and doesn't speak after that. I used GPT-4o-cluster. Not sure what's going on ? I created a new assistant and still same issue. https://cdn.discordapp.com/attachments/1211484481848873020/1439857568880132106/019a905a-e1cd-7558-ad31-708bec0c4de5-1763358488531-ff72e75f-8fba-428c-b595-a3942886672c-mono.wav?ex=691c0b5b&is=691ab9db&hm=ecf1b3f9a6c17353fa38bbe45f72b6c0f47d080c9b7323a3ea4ea07397b40e80&
