White void in top left corner of layout window

crash

#1

Hi my name is Aaron from New Zealand

I logged into my layout to work on a design project a few days ago to find this white void in the top corner- I am unable to use most of the tools on my tool bar and if I try and do anything Layout crashes. I have contacted my sketchup pro re seller but they can not fix the problem.

if anyone has any ideas I would really appreciate it
