[Python] RuntimeWarning: coroutine <aiortc> was never awaited

I am trying to use two Python libraries together: windows-capture and aiortc

Below is the code in my server.py:

import asyncio
from windows_capture import Frame, InternalCaptureControl

from aiohttp import web
from aiortc import RTCPeerConnection, RTCSessionDescription

my_channel = None
is_my_channel_open = False

async def offer(request):
params = await request.json()
offer = RTCSessionDescription(sdp=params["sdp"], type=params["type"])

pc = RTCPeerConnection()

global my_channel
my_channel = pc.createDataChannel("my_channel")
@my_channel.on("open")
def on_open():
# REFERENCE BELOW
my_channel.send("Hello from Python aiortc server!")
# REFERENCE ABOVE
global is_my_channel_open
is_my_channel_open = True

# handle offer
await pc.setRemoteDescription(offer)
# send answer
answer = await pc.createAnswer()
await pc.setLocalDescription(answer)

def setup_aiohttp_server():
app = web.Application()
app.router.add_post("/offer", offer)
web.run_app(
app, host="0.0.0.0", port=8080
)
print("This print will never happen")

def setup_windows_capture():
# Called Every Time A New Frame Is Available
@capture.event
def on_frame_arrived(frame: Frame, capture_control: InternalCaptureControl):
if is_my_channel_open:
# PROBLEM AREA BELOW
my_channel.send("data sent from on_frame_arrived")
# PROBLEM AREA ABOVE

print_capture_fps() # This prints the capture FPS once a second to console

# Starts the capture session
capture.start()
print("This print will never happen")

async def main():
task1 = asyncio.to_thread(setup_windows_capture)
task2 = asyncio.to_thread(setup_aiohttp_server)

await asyncio.gather(task1, task2)

asyncio.run(main())


My problem is that I'm trying to call my_channel.send("data sent from on_frame_arrived") in the PROBLEM AREA but it seems to completely break the on_frame_arrived function. Every second, the FPS is printed to console, but after calling this method, the FPS stops and I get this error:

C:\Users\Dzenis\AppData\Local\Programs\Python\Python313\Lib\site-packages\windows_capture\__init__.py:224: RuntimeWarning: coroutine 'RTCSctpTransport._data_channel_flush' was never awaited
self.capture.start()
RuntimeWarning: Enable tracemalloc to get the object allocation traceback


On the browser, I get "Hello from Python aiortc server!" printed, but I only get "data sent from on_frame_arrived" once, instead of an expected ~60 times per second
