Research direction

Read ui/fragments/CompressedExplorerFragment.kt around changePath at line 583 and archiveCorruptOrUnsupportedToast at line 622, then trace the asynchronous error callback. The fix is done when a corrupt or unsupported archive cannot trigger requireContext after the fragment is detached, without reproducing this crash.
