Oculus Quest/Windows Voip crashes after seamless travel with 2+ players

When I have 2 players using voice chat the game crashes after seamless travel. the 2 clients are playing on the Quest and connected to a server running on Windows. It crashes on each device. Am I supposed to be calling something to clear the talking players pre seamless travel? I’m using OnlineSubSystemNull.

I also had to disable this ensure in VoiceInterfaceImpl.cpp to get voice to work on Android:

ensureAlways(Amplitude >= 0.0f && Amplitude <= 1.0f);

crash on Windows:

This is the logcat output on the Quest but it’s just crashing due the Ensure, which is another bug.

Hi and news on crashing with seamless travel on quest?

I think the only workaround is to disable Voip when doing seamless travel

Any news on this? Getting the same error!
