Interactive avatar session is terminating prematurely shortly after it starts

We’re encountering an issue with the Streaming Avatar SDK for interactive avatars.

Specifically, the session is terminating prematurely shortly after it starts, regardless of the activityIdleTimeout value we've configured.

Even when we explicitly invoke the keepAlive() function, the session still ends unexpectedly.
This behavior has been consistently observed with SDK versions 2.0.12 and 2.0.16.
