How it was tested:
1. Created a new project
2. Added assets from ("REPRO.zip")
3. Added 4 copies of ("agate.psb") asset to the Scene
4. Open the Game window and turn on Stats
5. Open Profiler window (Window->Analysis->Profiler)
6. Enter Playmode
7. Recorded data

Expected result: 2D Animation package performance is the same or better than the previous version
Actual result: 2D Animation package performance is worse than the previous version

    It might be related to changes in how the 2D Animation package handles rig initialization in newer versions. You could try profiling the scene to see which processes take longer in Playmode. Also, reverting to an earlier stable version (like 2.1.x) or disabling unnecessary editor scripts during Playmode might help narrow down the issue.
