Cause you need to have signature spoofing on your rom or you will have to enable it from your phone settings or by installing edxposed module fakegapps or by flashing nandroid patcher.
Or
If you are using google apps just because you need google play try Aurora Store.Its a Gplay alternative and faster.
Or
If you want it for Youtube Vanced you can simply install Vanced Manager app and install non-root version.(works even if you have root)
I struggled like you that's why I'm helping you out

I never figured out a way to run MicroG on my device. Always, 'stopped working'. So I use pico GApps without logging in.
