Multiview, playing several streams at once in a grid, holds multiple active sessions in memory simultaneously rather than just one, which is a much heavier load than normal viewing. Several reports describe the app crashing specifically when multiview is running and the user switches away to another app, then back to it a moment later. Single-channel playback in the same app stays stable under the identical conditions, which is what points at multiview itself rather than the app being broken generally. If your crashes only happen in multiview, avoid switching apps while it's active, or drop back to single-channel viewing when you need to alt-tab away.

Player apps load the full visible channel list into memory at launch, and that load grows heavier as the count rises, even before you've clicked into a single channel. Lists pushing past roughly 18,000 visible channels start to destabilize on Firestick hardware specifically, since Firestick models carry noticeably less memory than a phone or a smart TV running the same app. Hiding channel groups you don't watch in the app settings is a genuine fix here, not just a workaround, because it directly reduces what the app has to hold in memory at any given moment.

A crash pattern that begins immediately after an update, with nothing else changed on your end or in your setup, is a distinct and recurring cause on its own: the update introduced a regression rather than exposing a problem that was already there waiting to happen. Clearing the app's cache and data after an update, then relaunching and logging back in fresh, resolves a large share of these without needing to wait for a follow-up patch to land, since it forces the app to rebuild its local state from scratch.
