Constant Sketchup Pro crashes with larger files (80-100mb) on Mac

We are having constant crashes on Sketchup pro using Mac’s in our offices with larger files (not huge files) around 80-100mb… (version 22.0.353)

You have to try re-open it over and over again, and then eventually it works (like a mystery), and you can save a copy of it, and then it works absolutely fine, albeit a bit slowish…

any suggestions to avoid the lengthy process of restarting / re-opening etc until it eventually works?
