Accept button on floating window doesn't work

I'm experiencing a weird problem that on the suggestion floating window, the Accept button doesn't work. When I click on it, nothing happens. The suggestion isn't applied to the code, and the floating window doesn't disappear either.

The reject button works as expected that no code changes and the floating window disappears.

I can accept it from Menu bar though

But since it's too inconvenient so I've set a key binding to accept it as a workaround.

Is there anybody having the same problem?

My environment:

• Chip: M1 Max
• macOS: 13.2.1（22D68）
• Xcode: 14.2 (14C18)
• Copilot for Xcode: 0.8.6 (49)
