Description

A cube constrained to a physics actor will start to jitter uncontrollably when interacted with. (see attached media and repro steps for more details)

 

Tested in the following

//UE5-Release-5.3-CL-27405482

//UE5-Release-5.2-CL-26001984

Steps to Reproduce
  1. Create Two cubes and scale one cube to 1.0, 0.1, 0.1
  2. Add a physics constraint actor, and add both cubes to the physics constraint actor
  3. Set all linear limits to Free in the physics constraint actor
  4. Simulate and interact with the smaller cube

Expected: 

Cube simulates physics normally

 

Result:

Cube will start to spin and jitter uncontrollably
