SketchUp 2019 unresponsive - log files?

[SJS66]

I'm having issues working with a large file containing imported objects & SketchUp Pro 2019 is frequently becoming unresponsive for extremely long periods of time (too long for my patients I'm afraid). So I'm doing a lot of force closing & subsequently losing work. I'm trying several strategies to help with performance issues i.e. using wire frame mode and layers to turn off visibility of the largest parts for the model, plus Outliner to select & zoom to extents to move the camera, but even still, simply trying to draw a couple of lines is proving difficult.

Is there anyway or where on your system you can get a log of what SketchUp is doing whilst it's "unresponsive" so I can see what exactly is causing it to freeze up?

I can't share the file due to NDA's on the project, so can't share any logs but if I can redact a log .txt file, maybe?
