Q has run out of tokens / stopped working, even though KIRO account shows credit

I'm using Q inside VSCode. It stopped working and it says that I've reached my limit. I clicked through the links provided but my account on Kiro shows lots of credit left. Why can't I use VSCode Amazon Q?

The report concerns Amazon Q in VSCode and includes screenshots showing a token-limit message despite credit in the Kiro account. Start by reproducing the limit message in the VSCode extension and compare the account and entitlement state; done means identifying why the available credit is not accepted or documenting the required account state.
