I can indeed reproduce the crash when running a clean app with RN 0.64.4, this module and the settings provided. If i use Java 8 - JDK 1.8.0 then there are some weird compile errors. Moving over to Java 11 seems to achieve a compile but then launch errors. Best bet is probably upgrading RN as the issue doesn’t exist on latest. That being said i will have a bash to see if i can resolve the crash.

Alrighty, I’ve managed to resolve the launch crash by making these changes.

Inside android/build.gradle change the following versions.

buildToolsVersion = "30.0.2"
classpath("com.android.tools.build:gradle:4.2.2")

Also inside android/gradle/wrapper/gradle-wrapper.properties upgrade the gradle distro a little.

distributionUrl=https\://services.gradle.org/distributions/gradle-6.9-bin.zip

Last but not least you will need to add the android:exported="true" property to your MainActivity inside android/app/src/main/AndroidManifest.xml which resolves the Android 12 targeting error.

@AliSaeed090 Can you please test to see if that resolves the issue for you. If it doesn’t then the alternative is to upgrade RN.

We don’t do anything specific not to support it, but RN 0.64 has been EOL for a long time. We can’t really spend resources fixing bugs in unmaintained RN versions.
