Microsoft SQL Server local report culture is not supported: 3072 is invalide culture identifer

Had the same error.

Turns out that it was my setting in Region -> Formats -> Format. When it was on English (World) or English (Europe), I would get this error. Setting it to English (United States) solves it.

I'm guessing that English (World) or English (Europe) were new formats with Windows 10, and SSMS is not prepared for it.

I think 3072 (0x0c00) is an invalid locale ID, at least according to this. So this looks like a corrupted Windows installation, perhaps from a flaky disk (eg. a byte overwrite of a locale 0x0c1a, which is the code for "Serbia and Montenegro (Former)").

You can try changing the current locale from Control Panel.
