Sorry for not updating recently.
I've been busy with work and haven't been able to do anything.

www\includes\modules\payment\stripe.php line 146

$amount_total=round($order->info['total']*$order->info['currency_value'],$decimal_places)*$multiplied_by;

I think it will be OK if you change it to the code below, but I haven't tested it.

if (MODULE_ORDER_TOTAL_INSTALLED) {
$order_totals = $order_total_modules->process();
$c = count($order_totals);
$c -= 1;
$order_value = $order_totals[$c]['value'];
} else{
$order_value = $order->info['total'];
}

$amount_total=round($order_value * $order->info['currency_value'],$decimal_places)*$multiplied_by;
