Amplify Studio says "Unknown Error" when click "Sync with Figma"

Does anyone experiencing "Unknown Error" when you "Sync with Figma" on existing synced UI components? It was working just few days ago, prior to minor changes on Amplify Studio UI recently. If I just re-create app with new app, then it works with same Figma URL and authentications. So suspecting issue on Amplify Studio's UI side, not Figma.
