UE crashes during project import on MacbookPro

Hello,

During an import of a project to my new workspace the UE crashes with the following error. I have tried other Macbooks from 2017 as well but the result is always the same.

My device:
Macbook Pro 2017

CPU: 2.5GHz i7

RAM: 16 GB

Graphics: Intel Iris Plus Graphics 640 1536 Mb
