Sketchup Make 2017 keeps crashing

Hi, I have recently been using Sketchup Make 2017 and it has been crashing either when I open the extension warehouse or try to save it. This only happens sometimes and it doesn’t save my work when it crashes and it’s very frustrating, please help!! A literal bug pops up on my laptop and says something about there being a bug. Is this from Sketchup or just my laptop? I’m using a MacBook pro Mojave version 10.14.4.
