Composer stopped working (Pro)

Has anyone found a solution to this?

I’ve had this problem now for about 2 weeks. Composer won’t open using Cmd+shift+i. It also gets stuck on generating if I do open it by right clicking on the top of the right hand pane.

EDIT: Using CMD+r in the composer window reset composer and fixed my issue
