How to reproduce:
To reproduce, spawn a character into the the level, pick up an item, walk forward and then throw the item by pressing z. You will see how the item appears to "slide" across the floor in a more exaggerated way than it used to.

How this was verified:
The most recent commit for the project in Unreal 4 did not have this issue. It was verified to happen after upgrading the project to Unreal 5.1 and it did not exist before.

After migrating to Unreal 5.1 from 4.26, items appeared to bounce and slide in ways that they didn't before. We fixed this by assigning a physics material to the physics box on BP_Item with a Friction of 3.0 and setting the Restitution Combine Mode to Max.
