Projucer crash after startup

I’ve had a number of crashes recently, a seemingly random short period of time after opening an existing project in the Projucer (5.3.2, macOS 10.12.6) I’m not quite ready to upgrade, so the issue may be fixed already, but here is crash report in case it gives any clues about something more deep seated

edit: and another

Have you tried compiling it and running in the bebugger?

Nope. I suspect it’s something to do with the update being available as it’s only happened since 5.4.0 been available, and it doesn’t really cause me enough issue to expend time investigating, but I figured JUCE team might be interested to know there is an issue.
