It looks like you're hitting the MS Windows cmd limitation.

"On computers running Microsoft Windows XP or later, the maximum length of
the string that you can use at the command prompt is 8191 characters. On
computers running Microsoft Windows 2000 or Windows NT 4.0, the maximum
length of the string that you can use at the command prompt is 2047
characters."
