V24 crashes - help!

Hi - i upgraded to SU2024 recently. Haven’t used it a lot since then but today the model I’m working in crashes every time I try and rotate an object. Its crashed 4 times in the last hour, just moving furniture around!
I’ve purged and Fixed from the Model window, but that hasn’t died it. Any ideas please anyone?

(its an 8.7 mb file so size is not the problem!)

Turn off the new graphics engine?

Make sure SketchUp is up to date?

Make sure macOS is up to date?

Open file in 2023 or 2022 and see if it works better?

Turn off the new graphics engine? - how?

Make sure SketchUp is up to date? - just installed, 24.0.554

Make sure macOS is up to date? - yes, automatic updates, Sonoma 14.5

Open file in 2023 or 2022 and see if it works better? - will do

Are you still on the Intel Mac, or did you recently upgrade to an M chip Mac? If so, try turning off anti aliasing.

I’ve turned off antialiasing and the new graphics engine and still happens

well ion the same panel, at the bottom, you can switch between engines.

is your profile still valid ? you have an older mac intel ?
those are on their last updates, the new engine might not be 100% compatible.

My profile is valid, and everything has been working fine. I switched off anti-aliasing and it still crashes, i switched between graphics engines and it still crashes.
