Summary
Animation Instability: without any changes to the Level Sequences or Cinematic Devices, several static mesh animations in-game have begun stuttering or freezing unexpectedly. However, when previewed directly from the Level Sequence, the animations play smoothly and as expected.

Additional Notes
The issue occurs regardless of sequence duration, number of keyframes, or meshes used
During gameplay, the animations stutter or freeze, often at specific moments, and sometimes the issue appears only after several cinematic cycles
The problem persists even in empty projects containing only a Level Sequence (migrated), a Cinematic Device, and Player Spawner
Rolling back to older project versions (as far back as December) does not resolve the issue.
