Current Behavior

Regardless of running the MultiVideoReceive scene on the Editor or the standalon Player it ends up crashing after completing the peer initialization and negotiation.

Expected Behavior

After pressing the AddTracks button, display both image feeds on the target objects.

Anything else?

A very similar behavior was previously reported on this issue, after cloning the project from the merge request and installing the package locally I was still able to replicate this bug.
