This issue started as soon as I “upgraded” from 2016 to 2017 versions of SketchUp. I had opened SketchUp Make 2016, received a popup that a new version was available. I clicked the button to get the new version on the popup and the install seemed to go fine. As soon as I opened the new version (having already deleted the old version, my mistake) Bugsplat fired up immediately, though there was no window, just the icon in the Dock. I figured I’d see a window with a stack dump of some kind.
I had originally downloaded and installed SetUp Pro 2016 and the 30-day trial had expired, where I was just using SketchUp Make.
I tried uninstalling SketchUp Make 2017 and trying again, with the same kind of failure. I then followed SketchUp’s instructions on how to completely remove all traces of SketchUp from my Mac, rebooting and trying to install again.
Now SketchUp Make 2017 at least gives me the Start screen and allows me to click the “Start Using SketchUp” button before crashing and Bugsplat starting immediately.
