!502 error when downloading form responses

Site: comparative-facial-perception-survey.netlify.app
Issue: !502 error when attempting to download form submissions as csv. I previously had no issues with a smaller volume of responses, but once receiving over 500 submissions I am no longer able to export the responses. I am a Pro member and should have been auto-upgraded in terms of Forms usage.

Please help!
