Windows: no running event loop, when using pyshark.FileCapture()

[DanielSchwartz1]

I've written a python code which is calling the FileCapture function like:
capture = pyshark.FileCapture(file_path)
to extract certain information from the capture.

On Unix systems all is working properly.
But on Windows clients (e.g. Windows 11), I receive the error:
"no running event loop"

I've also checked the other issues ongoing and I saw similar threads.
I've tried to close the capture with:
capture.close()

But it does not work anyway.

Expected behavior
I've expected to have extracted all information without the error "no running event loop"

Versions (please complete the following information):

• OS: Windows 11
• python version: 3.7
• tshark version: 4.0.10

Example pcap / packet
Does not work with any pcap file.

Do you have by chance a workaround for it?

Thank you!

I'm running on Windows 11 and it seems to be working fine for me?

• OS: Windows 11 22H2
• python version: 3.11.5
• pyshark version: 0.6
• tshark version: 4.0.10

import pyshark

capfile = "D:\\test.pcapng"
capture = pyshark.FileCapture(capfile)
capture.load_packets()
print(len(capture))

I fixed my problem - it is related to the python version.
At the end it was a matter to apply the workaround to be (again) compatible with Python Version 3.7.
It is described here: #642

I solved the issue by explicitly setting the event loop and passing it into FileCapture in Python 3.11.6

import asyncio
loop = asyncio.ProactorEventLoop()
asyncio.set_event_loop(loop)
pcap_file ='D:\\x.x.x.x_cap1.cap'
display_filter = 'tcp.analysis.retransmission or tcp.analysis.duplicate_ack'
cap = pyshark.FileCapture(pcap_file,eventloop=loop,display_filter=display_filter)
print(cap[0])
