The symptom and its scope
Record whether the crash follows one title, one navigation action or extended use. Device storage, app version and decoder behaviour can matter even while the account is valid.
Close unnecessary apps, check free storage and repeat the specific action once. Preserve the working profile before clearing app data.
Separate a source issue from a setup issue
If one source fails while another plays, record the exact affected channel or title and its selected quality. If every source fails, confirm the profile, account expiry and active-connection allowance through support. If one device differs from another, capture the player build and device model before changing the account.
A wired comparison changes the network path while a decoder comparison changes local playback. Keep those tests separate. Use the linked diagnostic articles to choose one controlled comparison instead of applying several resets at once.
Before a destructive reset
Keep a working profile and record the app version. Clearing app data can remove playlists, favourites and guide preferences. A factory reset removes more than the symptom you are testing and is not an appropriate first response to a single-source failure.
The support report
State “player closes unexpectedly”, the device model, app version, network type, account method, source, time and timezone. Include what still works and what changed during the test. Redact passwords, private playlist URLs, service codes, device keys and customer information.
