The Samsung S90D is a 2024 OLED television running Tizen, and when its apps will not open, crash, will not update or are missing, the causes are the network, the app's own state or the TV's software, and a short sequence fixes most cases. First check the network. Open Settings, General, Network, Network Status and confirm the TV is online; if the apps open and show a network error, restart the router and the TV, and test another device. A weak Wi-Fi signal causes apps to stall, so use the wired port if you can.
The checks in more detail
For one app, press and hold its tile on the Apps screen and choose Reinstall or, in Settings, Support, Device Care, Manage Storage, select the app and clear its cache and data, which signs you out. This often cures an app that crashes on launch. Update the TV and the apps. In Settings, Support, Software Update, install any update and turn on Auto Update. In Apps, Settings, turn on Auto Update for apps, or update each one from its tile.
If an app is missing, search for it in the Apps store; some apps are removed from older models or in some regions. If the store fails to load, check the date and time, which must be set automatically for secure connections, and the DNS, which you can set to automatic or a public service in the network settings. If many apps misbehave, the TV may be short of storage: in Device Care, Manage Storage, remove apps you do not use.
A factory reset, in Settings, Support, Self Diagnosis, Reset, clears bad states but removes settings and sign-ins, so note your accounts first. For streaming problems with one service, check its status and your account. If the Smart Hub itself is slow or freezes, unplug the TV for a minute and try again. A VPN or a router with a DNS filter can block some apps, so test on a phone hotspot. If apps still fail after these steps, contact Samsung with the model number and the app's name.
