Problem Mover 2.0 IK and Root Shipping Pack

Hello everyone. No one knows what I could have broken in GASP on version 5.7.2, but when I pack the game “shipping” using the launcher, the IK of the legs breaks (it doesn’t work) and any motion matching also works strangely. For example, when I roll, the character falls through the ground (as if its root bone is lower than the surface it’s sliding on) and then returns to the surface.

p.s I downloaded the clean version of GASP, and Mover 2.0 has the same problem when it’s packaged. If you pack the game in development mode, nothing breaks, just like in the editor. Everything works well.
