I experienced the same exception. In my case, the full file path was longer than the 260 character limit on Windows. Shortening the filename or the name of an intermediate directory was enough to get it below the character limit and it loaded without exception. One possible solution could be to prefix the path with \\?\ which allows longer paths on Windows (up to 32K characters I believe).
