Hello,
Go to Theme Options > FaceBook > remove the FB keys. Try Stripe after that. If it works then add the FB keys back. Then create test Stripe account and provide us with test access that we’ll be able to use to test the problem and find the correct solution https://infusiongroup.com/knowledgebase/how-to-test-the-woocommerce-checkout-process-using-stripe/
