Well, you left out the most important pieces: your active theme, the WooCommerce plugin, and the specific plugin you’re using to do the Stripe payment integration.
This is likely a WordPress plugin conflict, and not Cloudflare related.
But you confirm or rule out Cloudflare as the cause by temporarily pausing Cloudflare.
