Sage - Flexible Shipping Logger Issue

When i try configure any shipping method with Flexible Shipping Plugin I have Fatal error on cart and checkout pages: Fatal error : Declaration of FSVendor\WPDesk\FS\TableRate\Logger\ShippingMethodLogger::emergency(Stringable|string $message, array $context = ): void must be compatible with Psr\Log\LoggerInterface::emergency($message, array $context = )
Any idea how to fix it?
