Description:
After running the Open Beta build for roughly 40 minutes (though not always exactly 40 minutes), remote players are unable to see the lip sync animation for my avatar. Although the lip sync appears to work correctly from my perspective, it is not transmitted to or visible by other players.
Steps to Reproduce:
  1. Launch VRCHAT in the Open Beta build.
  2. Wait for around 40 minutes after startup (the issue may not occur precisely at 40 minutes every time).
  3. Observe that remote players no longer see the avatar's lip sync animations.
Expected Behavior:
Lip sync animations should continue to function and be visible to all players, regardless of session duration.
Actual Behavior:
After roughly 40 minutes of gameplay, the lip sync stops working for remote players, even though it appears normal from the local view.
* Using the "Reset Avatar" option does not resolve the issue.
* Using the "Rejoin" option also does not fix the problem.
* Restarting VRCHAT temporarily fixes the issue.
