[Python] BAC0: "RuntimeError: no running event loop" when connecting to a foreign device

I am trying to connect to a BACnet foreign device using the BAC0 Python library. Below is my script:

import BAC0

print(BAC0.version)

bbmdIP = '10.x.y.z:47808' # Replace with actual IP
bbmdTTL = 900
bacnet = BAC0.lite(bbmdAddress=bbmdIP, bbmdTTL=bbmdTTL) # Connect

print(bacnet.vendorName.strValue)
print(bacnet.modelName.strValue)

whois_results = bacnet.whois()
print("WhoIs results:", whois_results)

print(bacnet.devices)

bacnet.discover(networks='known')


However, I keep getting the following error:

2025-01-09 14:35:05,917 - INFO | Starting Asynchronous BAC0 version 2024.09.10 (Lite)
2025-01-09 14:35:05,920 - INFO | Using bacpypes3 version 0.0.98

What I have tried:

• 
  I tried running the script with different variations of BAC0.lite() and BAC0.connect(), but the error persists
  
  
• 
  I verified that my BACnet devices are accessible using Yabe software, where I can register and discover all devices successfully
  
  
• 
  I experimented with adding an event loop manually, but it didn't work
  

Why is asyncio.create_task() failing with RuntimeError: no running event loop, and how can I properly connect to a foreign BACnet device using BAC0?
