    some of you may say that this question is already answered but it is not , scapy was working very well but suddenly i had to format my computer after that i installed everything correctly , and i get this error every time i need to print ANY information in scapy classes like IP or TCP , etc :

    Traceback (most recent call last):
    File "C:/Users/work/PycharmProjects/Scapy/lesson3.py", line 20, in <module>
    print(send(IP(dst='192.168.100.1', ttl=(1, 4))/ICMP(), return_packets=True).summary()) # if return_packets are True then it will show a PacketList .
    File "C:\Users\work\PycharmProjects\Scapy\venv\lib\site-packages\scapy\sendrecv.py", line 300, in send
    socket = conf.L3socket(*args, **kargs)
    File "C:\Users\work\PycharmProjects\Scapy\venv\lib\site-packages\scapy\arch\pcapdnet.py", line 259, in __init__
    self.ins = open_pcap(iface, 1600, self.promisc, 100, monitor=monitor)
    File "C:\Users\work\PycharmProjects\Scapy\venv\lib\site-packages\scapy\arch\windows\__init__.py", line 914, in open_pcap
    if conf.use_npcap and isinstance(iface, NetworkInterface) and iface.ismonitor():
    File "C:\Users\work\PycharmProjects\Scapy\venv\lib\site-packages\scapy\arch\windows\__init__.py", line 596, in ismonitor
    return self.mode() == "monitor"
    File "C:\Users\work\PycharmProjects\Scapy\venv\lib\site-packages\scapy\arch\windows\__init__.py", line 590, in mode
    return POWERSHELL_PROCESS.query([_WlanHelper, self.guid[1:-1], "mode"], crp=False, rst_t=True)[0].strip()
    IndexError: list index out of range


    and this is the code of the program :

    send(IP(dst='192.168.100.1', ttl=(1, 4))/ICMP(), return_packets=True).summary()


    so every time i want to print any information i get that error like it is like stifling me and i have no idea about what is going on .
