So I was just making another video and I had to put in a bit of text. I decided I didn't want to use Arial so I clicked on the drop down box to change the font. As soon as I clicked the box, Hitfilm crashed. I thought maybe it was a one off thing and I reopened Hitifilm and tried again. Same thing happened. I tried a third time and the problem persisted.
I'm using a MacBook Air (13-inch, Early 2015), macOS Sierra, version 10.12.6
