Please I need its resurrection! It the great thing, but almost dead

I used it few years, now on php 8+ there are some issues, that I asked of people how to fix them.

1. On /wp-content/plugins/woo-poly-integration/src/Hyyan/WPI/Utilities.php on line 645 change to

} else {
				//20190630: old code used in previous versions of this plugin
			if ($polylang->curlang) {
				$polylang->curlang->locale = $languageLocale;
			}
			}

2. To make it work with variable products again in woo-poly-integration/src/Hyyan/WPI/LocaleNumbers.php string 97

$retval = $a->format((float) $input, \NumberFormatter::TYPE_DOUBLE);

I don’t remember what was the third.

Someone, please, don’t let this great plugin die, or resurrect it from the dead!
