  1. Resolution Note:

    This crash is unfortunately a result of either a bug or an otherwise behavioral difference in the emulated rosetta environment. After investigating ourselves as well as consulting with the primary developer at Microsoft responsible for the jitting implementation in mono we were unable to come up with a solution to all of the crashes the sample project encounters.

    An upstream bug was filed here: and work is being done to address part of the issues that were discovered.

    It is encouraged to run natively on the system architecture without emulation via rosetta as much as possible.

    This, unfortunately, happened with me again yesterday and all my game objects are gone and I have to start creating my whole scene again :(
