Particular LAYOUT file won't open, all others do

Hi, I’m on a Mac using SketchUp 2018. I can’t open a particular .layout file (size 48.8MB) and I get no pop-up message. All my other .layout files open. I’ve done lots of reading/searching, but the technical jargon is way over my head. Any help appreciated…


thanks + regards mymojo

The associated SKP file appears to be corrupted. Do you have the original file SKP file? Can you open it? Can you share it?
