Good afternoon, dear friends, first... please excuse my English, it's not good.
I have this beautiful error after updating

Unknown locale code: es-AR

[PrestaShop\PrestaShop\Core\Localization\Exception\LocalizationException 0]

I don't know whether it still is a problem. But in the past I have seen problems with two versions of the same language, as you have with es-ES and es-AR.
