Research direction
Start in asynchronous/asynctasks/PrepareCopyTask.java, especially onPostExecute at line 195, and trace the copy-folder flow that reproduces the crash on Android 11. Run the copy operation with the reported setup and confirm that it no longer crashes when MainActivity is not attached to the window manager.
