All my files have no errors! But then also in LOGCAT after the app crashes an error pointing to my MainActivity.kt file is present. Once I click on it, it points to -> setContentView(R.layout.activity_main).
One more thing. When I click on the LOGCAT thing it says "sources for android api 32 not found" and above it, it says " decompile .class file, bytecode version 52.0(java 8) ".
Just to let you know that, I have only build my layout whereas I was going to build the MainActicity.kt file later.
I was assuming it is because of api or sdk mismatch or maybe some syntax in my xml which is not imported or something like that.

BUTTON [ I was building a calculator and was trying for rounded buttons. When I did that it removed the boundaries too :(. I think I have imported something wrong maybe I am using some wrong import?]->
<Button
style="?android:attr/borderlessButtonStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@integer/margin"
android:padding="@integer/padding"
android:text="@string/divide"
android:textColor="@color/THEME1"
android:textSize="35sp"
app:cornerRadius="10dp" />
How it looks right now ->
