Choose the starting context
Inspect the installed Kodi version’s profile settings and decide whether startup should show a choice, use a named profile or return to the last-used context where available. Record the original behaviour before changing it. A shared television can otherwise reopen in a surprising library or layout.
For a hypothetical household, a person may expect their own view while the last session belonged to another viewer. That is a profile-selection question to establish before concluding the media library was deleted. Check the current profile name and available authorised sources first.
Use proper protection for private access
The official concepts page explicitly says profiles are not a security feature. Treat them as organisation and presentation choices, not a substitute for operating-system access controls or properly authorised server accounts. A hidden-looking source is not independent proof that another user cannot reach it.
If support is needed, provide Kodi version, expected startup choice, active profile and the exact missing or shared state. Keep private source paths and credentials out of screenshots. Confirm the startup behaviour after a normal restart, and retain a route back to the original profile before retiring an old setup.
