Critical error with WordPress version 6.1.1

We are using this plugin for years without any issues. Now we have updates our WordPress to version 6.1.1 – the module generates a critical error. The error occurs when the user fills in the donation form and hits the donate button. Then next page shows only a spinner and the message: “There has been a critical error on this page”. I can see in our Mollie account, that the form actually works, and “clients” are uploaded to Mollie.com. However, the payment can not happen, as the payment form/module is not loaded so no money can come in and the process end in error.

Please let us know how this can be solved, as nobody can make donations now to our charity through the website.

Thanks you!
