installation – Please help.I have tried all solutions but things have failed to work out.I don’t know what the problem is causing because it’s a new phone

I have a tecno phone with Android 8.1.0. YouTube go is my system app however l grew tired of using it because of it’s limited features and decided to install YouTube. But that’s when the trouble started. The app downloads till 100% and then shows that it is installing and then nothing, nothing at all back to square one and no error is shown. I have enough space, I have cleared data and cache for playstore, restarted the phone,even tried APKs but still nothing worked. What could be the issue? The only advice I have received so far is to root the phone. What should I do? other apps download and install just fine.
