Hi Sutorcen,
I was unable to reproduce the crash that you described on a Mac. Is there a specific template that you are using when you create a new 4.17 project? I tried with both a Blank Blueprint project as well as a Basic Code project, and they both opened fine in the Editor.
I do not think that this would cause the issue that you are experiencing, but we are aware of an existing conflict between the Nvidia driver and Metal. Since your Mac has a Nvidia card (mine is using an AMD card), try opening the ConsoleVariables.ini file and remove the semi-colon (
at the beginning of the following line: ;r.Shaders.Optimize=0
This will disable Metal, but may allow you to open the project if that conflict is actually what is causing the crash that you are seeing. If it does resolve the crash, you will be able to continue working on your project at the expense of some rendering efficiency. Once the conflict is resolved, you can replace the semi-colon and regain the benefits of Metal.
If that does not resolve the issue, could you please provide any additional specific information you may have about your repro that may help us to reproduce it here?
