We have an enterprise application being developed, and since the project inception, we're facing a constant crash only in OnePlus Nord devices.

We tried to reproduce in our devices, and it's not getting reproduced, but Firebase Crashlytics always reports it in live application. Description as:

cpe.java line 11

com.oneplus.theme.cpe.onViewAttachedToWindow

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.removeOnAttachStateChangeListener(android.view.View$OnAttachStateChangeListener)' on a null object reference       at com.oneplus.theme.cpe.onViewAttachedToWindow(cpe.java:11)       at android.view.View.dispatchAttachedToWindow(View.java:20272)       at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3455)       at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:2273)       at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1960)       at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:8228)       at android.view.Choreographer$CallbackRecord.run(Choreographer.java:1239)       at android.view.Choreographer.doCallbacks(Choreographer.java:1041)       at android.view.Choreographer.doFrame(Choreographer.java:953)       at android.view.Choreographer$FrameHandler.handleMessage(Choreographer.java:1163)       at android.os.Handler.dispatchMessage(Handler.java:107)       at android.os.Looper.loop(Looper.java:214)       at android.app.ActivityThread.main(ActivityThread.java:7711)       at java.lang.reflect.Method.invoke(Method.java)       at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:516)       at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:950)

At this stage, as it is working fine on all other devices, we couldn't pinpoint any code which could be causing this issue.

Being reported with many OnePlus Nord users, this issue brings our crash free % down significantly! How to fix this?
