The warning `/usr/lib/python3.8/asyncio/base_events.py:641: RuntimeWarning: coroutine 'Queue.put' was never awaited` was emitted when I pressed `n+enter` on the prompt to open the browser. I then needed to send the Ctrl+C signal to get out of the process.

This is the first time that this happened to me so likely not very common issue that might be hard to debug. Assigning Low priority for now, will escalate if I keep hitting this.
