TIFF Import - site survey - Drone Deploy OBJ - SketchUp Crash

Hello there,

I recently purchased a new DJI Drone to survey potential sites for music festivals. I build my plan view and isometric maps in SketchUp Pro 2018 on my Macbook Pro. Mac Specs below.

MacBook Pro (Retina, 15-inch, Late 2013)
2 GHz Intel Core i7
Intel Iris Pro 1536 MB
8 GB 1600 MHz DDR3

The Tiff image is 48mb. Sketchup just instantly crashes with no error message, completely shuts it down.

Also having problems importing an OBJ file for the 3D file of the site that I surveyed using Drone Deploy. My OBJ importer is SIMLAB 3D.
