error: resource android:attr/lStar not found…….

After searching for a long time, there is nothing related to LSTAR under my attr directory. The project has not added LSTAR related fields from the beginning to the end, but the project inexplicably reported this error, that is, it can’t run. It can run in the first minute. Suddenly it can’t run. Do you say it’s annoying or not

To get down to business, the reason is that Android. Core: core KTX: + is referenced in the third-party library, and then the system automatically updates to version 1.6.0, resulting in an error: resource Android: attr/LSTAR not found. Change the version to Android. Core: core KTX: 1.6.0, synchronize and compile it.
