[BUG] GASP Character Snaps/Stutters When Turning 180° in Packaged Build (OffsetRootBone?)

Thanks for the awesome GASP tutorial!
After packaging a project using GASP, I encountered a bug:
When switching to Free Mode (middle mouse button), the character jumps or stutters strangely when turning 180° to start moving.

This doesn’t happen in the editor — only in the packaged build.
I suspect it’s related to the OffsetRootBone node or how root motion is handled.
The issue seems to occur across all engine versions.

Has anyone else run into this? Any fix or insight would be greatly appreciated!

I’ve found the direction where this issue happens.
It occurs when I package the project using the Shipping build.
When I use other build versions, like Development, the issue doesn’t appear.
I’m still not sure how to fix it.
