We are getting a crash due to illegal state read ```java lan

Question

We are getting a crash due to illegal state read ```java lang IllegalStateException Reading a state that was created after the snapshot was taken or in a snapshot that has not yet been applied``` But we are not able to figure out which part of our source is causing this problem since all of the stacktrace points to android framework compose runtime and animation library Full stacktrace in the thread Note the crash is intermittent and we are able to reproduce it a few times when the app is changing orientation from landscape back to portrait Can anyone help us figure out how we can get to the root cause for this crash
