I did not give you a new plugin. It seems the only way to replicate the issue (regardless of the plugin version) is to have Stripe set to open by default, then click to select it again. There’s an open ticket and a developer is working on a fix for Event Espresso 4 core. You’re welcome to test the branch on your staging site when it’s ready for testing. For the time being maybe you can set the other payment method to open by default on the production site?
