Rhino 8 stops responding when trying to open existing files

Rhino Rhino for Mac
1

I am new to Rhino and have discovered that both in Trial version of Rhino 8 and now licensed version, I keep getting the ’Not responding” problem and need to force quit the app. I can open the file from within Rhino. What I have noticed is that Rhino takes a long time to open?

I was going to attach my System Information file but not sure how to do that to this text.

I would love to know how to fix this. Thanks

Is this happening in particular files? Can you post or send us one?
