Chosen Solution
I have downloaded the vanced tube from https://vancedtube.com/ and the installtion was successful. But the case is that but the YouTube app does not appear in the app launcher. I can not figure out the reason and looking for a help from some one who uses this app.
Vancedtube is a modded version of youtube. It is possible they are sharing the same package name. or Overwrites youtube app. So actual youtube app wont be shown as long as vancedtube installed
