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.
