Reproduction steps

Sorry, I have not been able to reproduce it myself. I can see crash reports on the Crashlytics dashboard for this issue.

Expected result

The following assertion should not be failed.

Assertions.checkState(
    timeline.isEmpty()
        || sessionPositionInfo.positionInfo.mediaItemIndex < timeline.getWindowCount());

https://github.com/androidx/media/blob/1.0.0-beta03/libraries/session/src/main/java/androidx/media3/session/PlayerInfo.java#L311

Actual result

Occasionally, the following exception is raised and the app crashes.

NOTE: I am using a slightly modified version of 1.0.0-beta03. I have added some debug logging code to the library, so the line numbers in the stack traces are not identical to the original 1.0.0-beta03.
