Hi @Kanchan-tech1994 - this SDK is no longer being maintained. Can you please use the new Kotlin SDK instead?

[Kanchan-tech1994]

Hi @izaaz ,

Thank you for your response.

As you can see, I am already using the Kotlin SDK (com.amplitude:analytics-android:1.+). Despite updating to the latest version of the Kotlin SDK, I am still encountering the same crash within the AmplitudeSDK.kt file, specifically at line 106.

Could you kindly assist in further investigating this issue?

@Kanchan-tech1994 my bad :) Missed the version number. I moved the issue to the right SDK.

@Kanchan-tech1994 - do you happen to register any plugins as well while initializing Amplitude?
