Condition: User must own zero (0) Warp Effects (No VRC+ subscription).
Steps to Reproduce:
  1. Launch VRChat and open the Main Menu UI.
  2. Click the Inventory icon at the top.
  3. Select "Cosmetics" from the side menu and locate the "Warp Effect" section.
Observe the UI: Since I do not have a VRC+ subscription, all specific effects are highlighted in yellow (locked). However, the "Random" option remains selectable.
  1. Select "Random" and equip it.
  2. Restart VRChat and attempt to view your avatar or travel to a different world.
6.Result: The bug occurs. The avatar remains a crystal, and world transitions fail due to a NullReferenceException.
