When trying to add the recommended items using B4A SDK Manager I am getting this type of error after an item has been added:

SDK Error said:
1. Open Tools - B4A Sdk manager.
2. Install all recommended items. This will make the switch to AndroidX. You can always go back to the previous SDK.

Example of error:
