I use com.github.navasmdc:MaterialDesign:1.5 without problem, but after upgrade an Android Studio when I try to build give me this error:

Failed to resolve: com.github.navasmdc:MaterialDesign:1.5
Show in Project Structure dialog
Affected Modules: app

I tried to search in the GitHub of the libray but there isn't a newer version. I uploaded all implementations, and don't solve it too. I upgraded and downgraded the plugin but nothing solved my problem.

What more can I do? I think to downgrade Android Studio in to version 3.6.

my build gradle files:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
