style attribute ‘android:attr/windowLayoutInDisplayCutoutMode’ not found

I am following a course for unity 3d, and am attempting to build my project for android. I am using Unity version 2019.3.9f1.

The build fails when creating a gradle project, but I am a complete beginner and have no idea what "grade" even means. Heres what the unity console prints out.

CommandInvokationFailure: Gradle build failed.
