Android Studio – Jetpack Compose preview stopped working in Arctic Fox with Patch 1

With the first patch for AS Arctic Fox Jetpack Compose previews stopped working.

I’m getting this error for all previews – even older ones, which worked fine a while back:

android.content.res.Resources$NotFoundException: Could not resolve resource value: [some hex value]

Are here any quick fixes for this? Clearing caches and the usual stuff did not work.

EDIT:
Looks like the problem is not always present. Some preview started working, while other are still failing.

EDIT 2:
This is happening in dynamic feature modules, when there’s a need for resources from the main module or painterResource() is being used (even is resource from the same module is to be displayed).

    This got fixed in AS Bumblebee, patch 2.

    Edit (copied from comments): It then got broken again in Electric Eel | 2022.1.1 and fixed again in Flamingo | 2022.2.1 Beta 4.

    As a temporary hack workaround I did this to get past the error and preview the UI elements.

    //import androidx.compose.ui.res.stringResource

fun stringResource(id: Int): String {
    when (id) {
        R.string.res_id -> return "Foo"
        ...
    }
    return "missing res_id"
}

    Same problem here with dynamic-modules project.
    Inspired by above answer, I’ve made another temporary workaround while waiting for Compose team to fix this.

    import androidx.compose.ui.res.stringResource as originalStringResource

@Composable
@ReadOnlyComposable
fun stringResourceSafe(@StringRes id: Int): String =
    if (BuildConfig.DEBUG) {
        val resources = LocalContext.current.resources
        try {
            resources.getString(id)
        } catch (e: Resources.NotFoundException) {
            "missing res."
        }
    } else {
        originalStringResource(id)
    }

    For me it starts working after run the application on a simulator (2022.1.1)
