Found the reason for this physics explosion! It's caused by "continuous collision detection", when two bodies are kept close to one another by a joint, and both are moving together at high speed. I suppose at some point it detects collisions that should not exist and it conflicts with the joint constraints.

I can't disable collision between bodies on both side of the joint since it's important they can collide (depending on what the player builds).

Attempt #3
Jolts HingeJoint3D is a bit different from the base HingeJoint3D and under documented at this point.

Still playing with settings but the device is at 10kg and the hinge properties are attached.
