It shows "insufficient credit" even though I have plenty of credit remaining. #deployment

Hello. I am currently on the free plan and have plenty of credits remaining (29 out of 30).

My netlify site name: https://jinclobert.netlify.app/

However, I am suddenly receiving a notification that I lack sufficient credits, and updates to Netlify are being skipped.I asked the Netlify AI for assistance with this issue, and it advised me to post about it here.I would appreciate it if you could help resolve this problem.
