Excel Sheet - TypeError: 'str' object is not callable

[orblatt]

Describe the bug
When I run vmonkey on 8d750691965fc57b365dce27a6e7231e (Found in VirusTotal) and it raised a Type Error:
TypeError: 'str' object is not callable

Also, at the beginning of the analysis, it raised the following line:
Error: [Errno 22] invalid mode ('rb') or filename: ''.

Here is the full description:
INFO parsed Function LIZOAS (): 4 statement(s)
INFO parsed Function MIZLOOZ (): 5 statement(s)
Traceback (most recent call last):
