I suggest that you update WooCommerce to 4.4.1 and Stripe to 4.5.2 and test.
If you are still experiencing this issue I suggest that you perform a conflict test.
Issues like this may be caused by either a conflict with your theme or with another plugin. You can read more about plugin and theme conflicts here:
https://docs.woocommerce.com/document/woocommerce-self-service-guide/
The best way to determine if the issue is being caused by a theme and/or plugin is to do the following:
1. Temporarily switch your theme back to the Storefront (https://www.woocommerce.com/storefront/) or TwentyNineteen (https://www.ads-software.com/themes/twentynineteen/) Theme.
2. Disable all plugins except for WooCommerce and Stripe.
3. Test to see if the issue has been resolved.
If that resolves the issue, then one-by-one you can switch back your theme and re-enable your plugins, testing in between, until you find the one causing the conflict.
If doing this on your live site is not possible, can you create a duplicate site? We suggest using WP Staging (https://www.ads-software.com/plugins/wp-staging/) if your hosting provider does not offer a staging server as an option.
I hope that helps you to figure it out.
