[UIXPress] Incompatibility with WooPayments (WooCommerce) plugin

I tried installing WooCommerce for the first time on a site where UIXPress was active.

After activating the WooPayments add-on, I get numerous red notifications constantly appearing in the bottom right corner. They say "Unable to connect," and there are between 10 and 20 of them every time any page loads.

Furthermore, the last notification always says "Critical error on this website."

I think there's a compatibility issue or conflict between UIXPress and this extension because if I deactivate either UIXPress or this extension, everything disappears.

The problem is that this extension is essential for WooCommerce to function.

Could you take a look at this?

Thank you in advance.
