Thank you very much for the response.
After this issue, i have disabled all payments and i have only enabled COD. and i have enabled the payment method for the location (Currently Single Location Mode)
and i have checked this with fresh installation and different browsers, but experiencing the same issue!!
I have really stuck at this moment!! 🙁
Here are some screenshots:
