Traceback (most recent call last):

(i,) = struct.unpack_from(format, self.input, self.read_cursor)
error: unpack_from requires a buffer of at least 4 bytes

Prompt this, what should I do?

It looks like a problem with one of the transaction inputs, the wallet tries to parse it with its internal algorithm defined in read_uint32[\tt] function but fails to do so. Try putting this part of the code in a try-catch block and see what happens, maybe it will skip problematic addresses and parse everything else successfully. Or maybe, you need to install an earlier version of Python.
