Brief explanation:

While we run our app´s release build type which has the already mentioned R8 config, hilt builts the proper ViewModel Providers, then the following crash appears (de-obfuscated code):

we´d tried with check whether it's the dependencies that a View Model takes, the type, but it doesn´t matter

also providing a custom factory solves the issue.

Anything else we can provide let us know.

Thank you.
