You can try disabling it with something like this:

disable "NullSafeMutableLiveData"
}
}

That looks to still be using the previous version. Could you upload a minimal sample project using 2.3.0-alpha05 that reproduces your issue?
or...@gmail.com
The sample at #1 should be using 2.3.0-alpha05 out of the box. I do not have a minimal sample at the time, sorry.
se...@google.com
That sample was using lifecycle 2.2.0 when I opened it. Upgraded it to 2.3.0-alpha05 and got an ObsoleteLintCustomCheck which is being addressed in
Gonna close this as not reproducible, and once you get a chance to reproduce it, just upload it here and would be happy to take a look.

Can you try this again:

Also reproducible locally on Android Studio 4.1 beta 3.

Still couldn't make see in the app. But was able to reproduce based on the class throwing the error and get a fix.
Description
Version used:1.1.0-alpha03
Devices/Android versions reproduced on:
as per
After updating to androidx.fragment:fragment-testing v1.0-alpha03 we're now getting following crash at end of test.
```
java.lang.NullPointerException: Attempt to invoke virtual method 'java.util.Collection java.util.concurrent.ConcurrentHashMap.values()' on a null object reference
at androidx.lifecycle.ViewModel.clear(ViewModel.java:125)
at androidx.lifecycle.ViewModelStore.clear(ViewModelStore.java:62)
```
Importantly this is test where we're mocking instance of ViewModel being used and issues seems to be related to associated changes to lifecycle-viewmodel v2.1.0-alpha01 which we now have a transitive dependency to. Specifically crash is occurring in following method because mBagOfTags is null
```
final void clear() {
mCleared = true;
for (Object value: mBagOfTags.values()) {
// see comment for the similar call in setTagIfAbsent
closeWithRuntimeException(value);
}
onCleared();
}
```
