Downloaded experimental build, no issues noted and scene works fine (same file)

Good morning

The report I posted was generated after launching Blender via terminal.
I think the Crash log, will be the one I originally loaded at the start of this post. I will try 2.82a

Just done it again via terminal and it crashed almost instantly. I've copied the crash report (hopefully the right one and posted it on the second link as you said the number is P1175

That was the crash report that was generated by my mac, is there a different one?

It's hard to say what steps to take it happens even with the default cube sometimes. Seems to be when I'm just adding a simple material using the principled shader.

Sorry if this is in the wrong section but it's the only place i could find. this only happened in 2.81 2.8 was stable on this machine (i downloaded the beta shortly before and the same issues occurred so i deleted it and continued with 2.8 unti2.81 was released and then I downloaded that, and issue still happens)
