After upgrading to AndroidX, all of my projects have broken.
This is the error in the latest project:

The Additional lib folder is located in "C:\B4A"
All the latest SDKs are installed.

Were there any additional steps i had to take while upgrading to AndroidX? I followed this tutorial.

After going through this answer, I replaced
B4X:
#Extends: android.support.v7.app.AppCompatActivity
with
B4X:
#Extends: androidx.appcompat.app.AppCompatActivity
Now I get this error:
