Android build suddenly starts failing with : resource android:attr/fontVariationSettings not found

Our android build started failing all on its own without a single line change for 2 days now.

This is the error message:

/Users/shroukkhan/.gradle/caches/transforms-1/files-1.1/ui-5.11.1.aar/baa8b66e2e52a0a50719f014fc3f1c32/res/values/values.xml:40:5-54: AAPT: error: resource android:attr/fontVariationSettings not found.

As I understand this is related to android support library version mismatch, so i have forced using same library version . However, the problem has persisted. Here is the root level build.gradle:

I have tracked it down to most likely candidate : io.smooch:ui:5.11.1 ( because the error states : .gradle/caches/transforms-1/files-1.1/ui-5.11.1.aar/baa8b66e2e52a0a50719f014fc3f1c32/res/values/values.xml:40:5-54: AAPT: error: resource android:attr/fontVariationSettings not found. ) . However, no solution proposed online has been working.

Does anyone have any idea whats going on ?
