Error while building app on android

[ashvini23may]

Hi, I am trying to build and install this source code on android but getting below error.

The minCompileSdk (31) specified in a
dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties)
is greater than this module's compileSdkVersion (android-29).

If I change compileSdkVersion to 31, then getting kotlin version mismatch errro

/.gradle/caches/transforms-3/0453560b92b97629cdc21df2bfebd566/transformed/jetified-core-ktx-1.9.0-alpha02-api.jar!/META-INF/core-ktx_release.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.6.0, expected version is 1.1.16.

and if I change ext.kotlin_version = '1.6.0' getting this error

I changed to Compile SDK version to 31 and now I get duplicate kotlin dependencies.
It seems to be because the build in pulling in two different versions of jetified-kotlin-stdlib (1.8.10 and jdk-1.3.72)

@ashvini23may I updated the 'Module Settings' for all projects and subprojects to Compile SDK version 33 and set kotlin-stdlib-jdk7 dependency to version 1.8.20-Beta and now it builds

I also had to get rid of "apply plugin: 'kotlin-android-extensions'" (deprecated) and replaced with kotlin-parcelize

The consequences of the 'kotlin-android-extensions' deprecation are deeper than I had thought.
Ex: BlueMS uses kotlinx.android.synthetic.main.fragment_color_ambient_light which is no longer available
