We have confirmed an issue where, if your Windows "Region and Language" setting is set to a language other than Japanese or English (Japan/United States), the game may experience black screens or significantly longer loading times. We sincerely apologize for the inconvenience this may cause.

We’re working on a fix, a patch will be released at a later date.
In the meantime, you can temporarily avoid the issue by setting your Windows language to something other than the following:

Indonesian, German, Italian, Spanish, French, Dutch, Belgian, Portuguese, Brazilian Portuguese, Luxembourgish, Swiss, Greek, or Turkish.

We apologize again for the inconvenience and appreciate your patience until the patch is available.
