  1. Resolution Note:

    This crash happens because the Burst package was copied into the Assets folder, at this path:


    This is not supported and will cause errors, like the crash reported here.

    These options are supported for installing the Burst package:

    * Adding {{"com.unity.burst": "1.8.12"}} to Packages/manifest.json
    * Putting an unzipped Burst package into Packages/com.unity.burst
