ViewPort Device Customize Crash

Fuse version 1.7.2 (build 15505)

Windows 10

Open/Create a project -> Click on Menu Items: Viewport -> Device -> Customize…

The application just crashes, no message, no warning, just disappears of the process stack.

Do you have any other details to share about your system?

That menu item should open a .json file in a text editor. Do you have Sublime Text installed? Do you have a default program set to open .json files with?
