Java.util.concurrent.RejectedExecutionException when using WorkManager

I am using work manager and kotlin coroutines

implementation "androidx.work:work-runtime-ktx:2.0.0"
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.0'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.1.0'

My worker class extend CoroutineWorker

and I schedule like this

private const val WORK_TAG = "myWork"
  private val constraints = Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build()

  fun schedule() {
         val work =
            OneTimeWorkRequestBuilder<MyWorker>().setConstraints(constraints).setInitialDelay(6, TimeUnit.HOURS)
                .addTag(WORK_TAG).build()
        WorkManager.getInstance().enqueue(work)
    }

In Google Play console I notice some crash on some Android version (https://ibb.co/DzBkpzy)

According to the official release doc, a fix was implemented in Version 2.2.0-rc01.

Fixed a bug in the AlarmManager implementation that causes the Service to shutdown prematurely and resulting in a RejectedExecutionException in rare cases

This has been fixed in a newer version of WorkManager. You can use versions 2.0.1-rc01 or 1.0.1-rc01.

ScheduledThreadPoolExecutor@1c2ffc76[Terminated

The workmanager tried to schedule the task on a terminated threadpool. Since that thread pool is not controlled by you and it does not seem to be a common issue it would be extremely difficult to create an actual fix for this.

At most you could try reporting it as a bug in the androidx library, but without more information it probably can't be 'fixed'
