    I started seeing random crashes at runtime (after 1-2 minutes) in 
    Unity.Physics.Solver:ScheduleSolveJacobiansJobs
    after updating unity and some packages:

    • unity 2022.3.0f1 -> 2022.3.2f1
    • physics 1.0.8 -> 1.0.10
    • burst 1.8.4 -> 1.8.7
    The crash has occurred both with burst enabled and disabled.

    I've reproduced the crash in unity 2022.3.1f1, physics 1.0.10, and burst 1.8.7

    I have not been able to reproduce the crash in 2022.3.0f1 with any combination of packages, so it seems like the issue is from the unity version update.

    Full stacktrace:

    Hello, I've been having the same log when my editor application crashes.

    I was creating and destroying a lot of projectile entities. (rigidbody, collider, and a lifespan component to destroy it after some time)

    I saw that when the projectile prefab is a single entity, my editor doesn't crash.
    It crashes when I have a child under the projectile prefab.
    (i was also keeping a tag component on the child to prevent it from being destroyed because its an empty entity)

    A workaround to this issue I think is not having any children under rigidbody objects.
