In your settings you have vp8 disabled, vp9 and av1 are not supported for end-to-end encryption.
Does it start working if you enable vp8 as a codec?

No, it does not work.

Did you ensure that you were actually publishing and receiving vp8 ?

I just tested this on browserstack with iOS16 and chrome as a browser. I see the same behaviour as you.
The reason for this is probably the fact that browserstack doesn't send any updated video frames (as the video is black/static). In order for a LiveKit track to be successfully published and broadcasted to other users server side, media needs to be flowing. This does not seem to be the case here.
I'll close this as won't fix, but feel free to re-open if you can reproduce this with an actual device and a working camera.

reopening as @AurimasG12 can repro on a real device
