There are a couple things I have sent crash-reports already for each occurrence, but I have figure some workaround for insta-crashes.
- if you could create or open a project but crashes on hit Play: disable Magic Leap plugins to Fix.
- if you tried to open a blueprint only project and it crashes before editor opens: delete Build and Intermediate folders and try open again. For C++ projects you need to right-click the .uproject file and select Generate Visual Studio Files before trying to open the project
