java.lang.ClassNotFoundException: Didn't find class "kotlinx.serialization.json.Json" on path: DexPathLis

When dexguarding the APK and running Kotlin from JSON to data serialization, I'm getting this crash exception: java.lang.ClassNotFoundException: Didn't find class "kotlinx.serialization.json.Json" on path: DexPathList. However, it is working fine in debug mode.

I tried to include all Kotlin serialization classes, but I'm still getting the exception.

`java.lang.NoClassDefFoundError: Failed resolution of: Lkotlinx/serialization/json/Json;

Caused by: java.lang.ClassNotFoundException: Didn't find class "kotlinx.serialization.json.Json" on path: DexPathList`

Attach a code snippet or test data if possible.

Expected behavior

Environment

• Kotlin version: 1.8.0
• Library version: 1.6.3
• Kotlin platforms:
• Gradle version: 7.4
• IDE version (if bug is related to the IDE) [e.g. IntellijIDEA 2019.1, Android Studio 3.4]
• Other relevant context [e.g. OS version, JRE version, ... ]

Not sure what can be the case, since Json is a regular class and should be processed just as any other usual class. Maybe -keep class kotlinx.serialization.json.** { *; } would help? If possible, please attach your project here or in another github repo because it is hard to say what happened without a reproducer.
