I'm on a Mac and the game crashes to desktop when loading some common objects#1382

Mac OS 10.14.6
Whenever I load certain workshop items or objects tts crashes to desktop.
Using either launch options (eg. metal) makes no diffrence.
I’ve checked the steam files etc. Turned off the fps counter/overlay etc.
I’ve attached a log of the crash. Both the tts and OS logs.
I’ve been having this problem for some time and trying to fix it.
The friends I play with don’t seem to be having this problem.
Strangly in some instances if they host the game and load the objects I have no crashes.
However in single or multiplayer if I always crash.

Looking at the logs it seems to be something to do with Unity and the number of points on meshes.
Is there a way to increase the ram limit availble to tts? I have more than enough to spare on my system? The crash seems to be assosiated with the ‘fallback handler’.

Help very much appriciated.

Throw that thrash away and get an actual computer with windows.
