Didn't find class "android.support.v4.app.CoreComponentFactory"

what I tried:

I tried cleaning the project and rebuild many times, and I also tried (Invalidate Cashes and restart from the File menu), I also tried adding android.enableR8=false on gradle.properties but it didn't work. i Also tried adding -keep class androidx.core.app.CoreComponentFactory { *; } on the proguard-rules.pro file. this error has been driving me crazy please help

sorry for having the error written in a weird way I had to put 4 spaces on each line because of stack overflow.

Full error:

I fixed the problem by removing these two lines from the manifest file

 tools:replace="android:appComponentFactory"
 android:appComponentFactory="android.support.v4.app.CoreComponentFactory"
