Error with Android 12

Samsung Blockchain
1

I have recently updated my phone to Android 12 and the app I have created using Samsung Blockchain SDK is now giving the following error. I have updated the SDK versions as follows:

buildToolsVersion = "31.0.0 "
        minSdkVersion = 24
        compileSdkVersion = 31
        targetSdkVersion = 30

Would appreciate any input on why I am getting this error about KnoxAndroidKeyStore.

Thank you.
