I started getting this issue on 2019.3.10f1 when started using Physics.Simulate. I am running Simulate() a few hundred cycles of fixedDeltaTime, then reusing the scene by adding and destroying items, then simulating again. Editor crash was guaranteed to happen after a consistently irregular time. Crash was not happening on the standalone build, only in the editor.
I just updated to 2020.1.0b9 and can confirm the issue is now gone along with my days of sorrow.

This still occurred on 2019.3.0b8 but happens much less frequently than in 2019.2.4f1. It occurs when parenting a inactive non-kinematic rigidbody gameobject to another gameobject and then setting it to be active. I wish I could look at the actual code to see what exactly is causing this crash. Are there any known workarounds?

Our team is also experiencing this issue in 2018.4.2f1 and 2018.4.3f1. Is there any information on when the fix will be resolved in 2018.4?

Correction: The bug doesn't occur within the editor; it only affects standalone builds of the game.

This bug affects my project, as well. Because of this editor crash bug, I can't update to Unity 2018 yet, and continue to use Unity 2017. I really hope that this bug can be fixed at some point in the near future.

I'm working in an open world and this issue is affecting my project as well.
In my case it often happens when chunks of the world are unloaded and I found that forcing rigidbodies to sleep 1 frame before destroying them helps preventing the crash, it's doesn't prevent all the time, but reduces the frequency.
