Cannot use with PHP 8.2

We have just updated to the latest version of the Woo Commerce Boost Sales plugin 1.5.6

We are not able to use PHP 8.2 with your plugin as it causes this error on the cart page and this means we can’t update the theme or comply with the hosting company.

Please advise urgently what the solution is, thank you.

Kind Regards
