Captivate Mac 2019 crashes recording a video demo

New to Captivate, just downloaded trial. Trying to record a video demo (talking head to overlay on a presentation). Seems like I’m on track, but as soon as I start to record, captivate freezes or quits. Every time. Mac running 10.14.2 with 16 gig ram and at least 30 gig hd space. captivate 11.0.1.266. Any ideas? I want to like this, there must be a fix…
