Model fails to generate, please help?

Hello. I'm having an issue with the Kling 3.0 Omni model I use on your SeaArt platform. The model isn't generating content. Generation doesn't start, it fails immediately, and I get a message saying "Your credits have been refunded." This problem has been going on for weeks now. Honestly, my subscription plan will be renewed in three days, but if support doesn't resolve this issue, I doubt I'll renew. Please consider my request for assistance. Federica federicatp.7@gmail.com
