When I close down VictronConnect (click on left-most red traffic light, top left of window) more often than not it crashes with the macOS error message "VictronConnect quit unexpectedly.". I'm running version v5.38 on my MacBook Air running macOS Mojave 10.14.6. I can't remember if I saw the problem with the previous version of VictronConnect. All other apps are behaving normally.
Clearly this isn't a major problem, just a bit of an inconvenience, but it'd be helpful if it could be investigated and resolved.
