RTSP error: Passing coroutines is forbidden, use tasks explicity

Hi,
After a few recent upgrades, my webcam is not displaying anymore in Lovelace.

I get the error Passing coroutines is forbidden
However, I can still hear the audio

Lovelace card:
For testing, I minimized the Lovelace card to the minimum

type: custom:webrtc-camera
url: rtsp://rtsp:[redacted]@1[redacted]:554/av_stream/ch0
title: westcam1

When open the RTSP stream in VLCplayer, I can see the video just fine.

I checked my logs, I checked the docs and the forums, but could not find a solution.
