Unable to authorize card. No response from Stripe.js

Good day. I’m currently having errors on the stripe add on as the for submission is not working: Screenshot by Lightshot
I already setup the live and test API keys, as well as the webhooks.
The form is currently on test mode for stripe.
I already tried to deactivate all plugins and also tried to activate default twenty twentyone theme. But still no luck.
I also sent an email to support but they suggest to post on the forums. Please advise. Thank you

Here is the page URL for the form: https://lashquiz.com/slide-checkout/
Please advise. Thanks
