Siri AI keep saying 'I’m having trouble with the connection' on my MacBook Pro M4

My MacBook Pro M4 has all the right settings to use Apple's new Siri AI, and the software is fully installed. However, every time I try to use it, Siri keeps saying "I’m having trouble with the connection. Please try again later." The only prompts that worked were simple ones like "Hi or "What time is it".

• Cleared my iCloud storage
• Turned off and on Siri AI multiple times
• Restarted my MacBook multiple times
• Apple Account region is in Taiwan, which I believe is available
• Has been accepted on the waitlist, and installed the new Siri AI
• Language is set to English (United States)
