I have a problem with WooCommerce Multi Currency

Hello, I have a problem with WooCommerce Multi-Currency, when I am at checkout, and when I need to go to the second step, the website is stuck and have a loader on screen, I tried everything and I disable one by one plugin to see where is the problem and I found that problem is with Multi-currency plugin. Can you please help me with that?

Here is the video where the site is stuck, you cannot see because the site is under maintenance and I need to create a new account, so you can see where is the problem. If we cannot find a solution to this problem I would love to refund the money.

Here is the video:
