Same questions have been asked but they didn't work for me , In the start I was using the latest version of work manager which is 2.7 alpha 3 but I downgraded since its only compatible to android 12 preview sdk , The error still remained there !
It cannot instantiate the worker because those dependencies are included in the constructor of the worker , It was working before I added them but there's no benefit of hilt if I can't add them so here's the situation :
Manifest does not contain any configuration related to work manager !
Application Class :
@HiltAndroidApp
class TimelineApp : Application() ,Configuration.Provider{
@Inject
lateinit var workerFactory: HiltWorkerFactory
override fun getWorkManagerConfiguration() =
Configuration.Builder()
.setWorkerFactory(workerFactory)
.build()
}
Worker :
@HiltWorker
class DriveSyncWorker @AssistedInject constructor(
@Assisted val context: Context,
@Assisted workerParams: WorkerParameters,
val dependency: StorageHelper,
)
Noticed : its not using HiltWorkFactory !

Since you are using work manager version above than 2.6.0-alpha01 , Work Manager version above 2.6.0-alpha01 uses startup initializer Read Here
Add this provider to you app AndroidManifest.xml:
<application ... >
<provider
android:name="androidx.startup.InitializationProvider"
android:authorities="${applicationId}.androidx-startup"
tools:node="remove">
</provider>
</application>
