Yeah we are also getting a lot of random crashes. Most seem to be related to the Metal framework. I have reverted to Beta 2 for now which seems far more stable but sadly produces much inferior results in our testing.

Hi, this is a known issue that Metal is working to resolve. I’m not sure of any workaround unfortunately.
