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
Component used: lifecycle-viewmodel
Version used: 2.8
Summary: the migration of ViewModelProvider to KMP seemingly reverted a 2 year old fix to an issue that had to do with desugaring for compileOnly dependencies in a library project.
Lifecycle 2.5.0 alpha accidentally broke backward compatibility, this was quickly fixed in Lifecycle 2.5.0-rc02, see this issue for context: https://issuetracker.google.com/issues/230454566
The fix was here:https://android-review.googlesource.com/c/platform/frameworks/support/+/2108693
The recent migration of ViewModelProvider.Factory to KMP seems to have reverted the fix:https://android-review.googlesource.com/c/platform/frameworks/support/+/2966765
As a result, the original runtime crash has surfaced again in lifecycle-viewmodel 2.8, as reported here:https://github.com/square/leakcanary/issues/2677
Someone created a repro at the time, you could probably reuse that to repro after updating the dependencies:https://github.com/dougnazar/leak_viewmodel
