New forces applied besides gravity or bug?

Hi. I had a 4.26 with Chaos enabled and ran a simple test. Tick → Mesh → AddForce( 980 * GetBodMass())

Which with gravity enabled will keep the object suspended in air.

Today I moved this project to UE5 and running the same test will result in the object slowly drifting towards the ground until collision. If you disable gravity, and instead use AddForce(-980 * GetBodyMass()) then you will get 4.26 + Chaos results which is a hovering object.

Is there anything else going on with forces that I might be made aware of for these tests? I’m pretty sure the desired result should be a hovering object.
