Verified by ch...@google.com.

Thanks for sharing the dump offline. I reproduced a compiler issue from the dump, which could trigger both the issue in comment #1 and the IncompatibleClassChangeError mentioned in comment #4. The fix has now landed and is present from R8 versions 3.2.62 and 3.3.37.

It would be great if you could confirm if R8 3.3.37 works for you.
