Could be that your dinput8.dll is infected by a virus.
You can try https://support.microsoft.com/en-us/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system
Or running a Antivirus check.
Could also be that Battleye is just randomly blocking files. It does that from time to time. In that case it should work of you try again on the next day.
