1. Have you saw crash in real device or only in simulators?
2. Do you use dynamic feature for language ID?

Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

Second crash in the description is from a real device. Experienced it myself on two different Xiaomi phones, plus lots of crashes from users in the Google Play console.

Dynamic features are not used in the application.
As a wild guess, I have downgraded build tools from 31.0.0 to 30.0.3, compileSdk from 31 to 30, and moved all work with Language ID to the service in a separate process (just to be sure that crash can kill secondary process instead of main). This combination is in beta for 2 days by now and I don't see any SIGSEGV crashes.

Hmm, I feel the crash might be something related to separate/secondary process.
I also changed compileSdk and targetSDK to 31 but still cannot repro this issue.

On the contrary, there was no separate process before, when crashes started.
In the new build (with the aforementioned changes) I can see SIGSEGV crash, but only one instead of dozens and it has a bit different backtrace:
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
liblanguage_id_jni.so (offset 0x11e000)

Description
Version used: 1.0.0-alpha11
Devices/Android versions reproduced on: irrelevant
I have a fragment like this:
<fragment
android:id="@+id/teamDetailFragment"
android:name="com.optima_apps.fkcz.ui.team.teamdetail.TeamDetailFragment"
android:label="{player_name}" <== PARAMETRIZED LABEL (from a plain string argument)
tools:layout="@layout/fragment_team_detail">
<argument
android:name="player"
app:argType="com.optima_apps.fkcz.models.Player" /> <== CUSTOM CLASS ARG TYPE
<argument
android:name="player_name"
app:argType="string" />
</fragment>
When parametrized label is used in combination with custom class argument type on a fragment, the app crashes when activity is recreated with a saved instance state. To reproduce, have a fragment configured as shown above, then in Developer Options enable "Don't keep activites" to force activity to destroy as soon as you leave it, then return to activity and it should crash like below:

I have already Googled this a bit and this could be the solution:
When I change the label to be a static string, the library never goes into part of code that's crashing, and everything works properly, so I'm sure the issue is not on my side.
If you need any additional info I'm here.
