In my Google Play Console I am seeing a lot of ANR clusters related to QtNativeInputConnection. I've also noticed some crashes, but only a few and mainly in the pre-launch reports. Here are some ANR examples:

From what I've seen all QtNativeInputConnection methods are affected, but I haven't been able to replicate any of their related ANRs on my devices. However I noticed a peculiar warning in the Android Studio logcat when the app is being closed and it might point to the issue:

Input channel object '4a37f1 com.gsoftteam.freecellmobile/org.qtproject.qt.android.bindings.MyQtActivity (client)' was disposed without first being removed with the input manager!

Another thing I noticed is that the Handler() constructor is deprecated https://developer.android.com/reference/android/os/Handler#Handler() ,but it's being used in showSoftwareKeyboard and hideSoftwareKeyboard methods from QtInputDelegate . Maybe Handler(Looper.getMainLooper()) should be used? However I doubt there is a connection between my initial report and the use of this deprecated constructor.
