Clear the temporary files first
For the 2023 Fire TV Stick 4K Max running Fire OS, open Settings, then Applications, then Manage Installed Applications. Select the affected app and choose Clear Cache. Launch it again and return to the same screen or programme that stalled. If the app launches and keeps your sign-in, play one item and then open its guide. This makes it easier to tell whether the original fault returned.
Save what you need before clearing data
Clear Data in the same screen is a separate, more disruptive action. Expect to set up the app again and possibly lose local favourites or settings. Record the app publisher and version, confirm you can sign in again, and use the app’s own export if it provides one. If Fire TV shows a storage warning across multiple apps, check what is taking up space and remove a large unused app. Repeated cache clearing will be temporary if the device is filling up again.
