Thanks, folks. All fixed.
I turned everything off, as suggested, then started up again but had the same issues.
I ended up reinstalling all software and updating drivers. Sound settings had the RODE mic and the laptop mic simultaneously activated during FB live streams, for reasons unknown, so I fixed that using OBS settings.
