Roblox Studio crashes during Team Test with Voice Chat when another player joins or you join them

Issue:
Roblox Studio playtest crashes and closes immediately at Step 4. It also sometimes crashes when changing audio input devices.

Steps to Reproduce:

  1. Insert VoiceChatService.
  2. Set EnableDefaultVoice to true.
  3. Set UseAudioApi to Automatic or Enabled.
  4. Start a Team Test and either join another user or have them join you.

Disabling UseAudioApi and EnableDefaultVoice fixes this issue. It can’t be reproduced by everyone in the Team Test. There are no errors in the output upon crashing.
