Cannot sign into Youtube

i cannot sign into YouTube apps,when ever I click on YouTube icon it just goes off in my Samsung tablet. Can I find a solution to solve this problem?
 
Just restart your device in safe mode...then go-to YouTube app...now you see that you are logged in..
Then again restart your device in normal mode...
It works.
