Open the Settings app on your Android device and tap Apps.
In the list of applications, tap YouTube.
Next, click "Storage".
If you see the Clear Cache option, tap it, otherwise tap Clear Data and then Clear Cache.
Now restart YouTube and check if the black screen issue persists.
Fix 2: Force stop the YouTube app.
Sometimes all you need to do to fix issues like a black iceland telegram data screen is to force close the app and open it again.

Tap YouTube in the list of apps.
