Mac crashes when using UE 4.25

Hi,

I am using UE4.25. After I start working on the first level of the game the computer crashes and it restarts. The level I am working on is basically empty. I am trying to create a small platform using the landscape tool. Therefore nothing complicated.

My computer is a MacBook Pro (13-inch, 2017)
3.1 GHz Dual-Core Intel Core i5
16 GB 2133 MHz LPDDR3
Intel Iris Plus Graphics 650 1536 MB
I have around 23 GB available of storage and I have downloaded the latest Xcode beta.

Any idea what is causing this issue?

Thanks,

Alessio
