Hi,

Try to add the following code snippet to the Custom CSS area in Theme Settings to fix this issue.

.woocommerce-Price-currencySymbol {
   font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
}

Regards
