DataStore Component used: androidx.datastore:datastore-preferences-core DataStore Version used: 1.1.1 Devices/Android versions reproduced on: MacBook Pro M1, MacOs Sonoma 14.4.1

This issue only occurs when using a "distributable" either using the runDistributable gradle task or by launching the .app generated by the createDistributable task.

It works perfectly when running the app through the run gradle task.

Writing on Datastore<Preferences> throws java.lang.ClassNotFoundException: sun.misc.Unsafe, creating the datastore and reading from it works perfectly.

This simple project allow you to reproduce the issue: https://github.com/Julien-Boulvert/datastore-issue-demo
