[Bug] Anthropic API Error: Rate Limit Reached on conversation initialization

Bug Description
I am instantly hitting "API Error: Rate Limit Reached" when I start a new conversation with Claude. This occured last night after enabling "Fast Mode" with Opus. However, this morning when I attempting to start a new conversation, Even with Sonnet 4.6, I instantly get the Rate Limit error message. With Max Subscription, I am unable to use Claude Code at all. Please help
