Start at LocalMedia.java:336, where generateLocalMedia is called from PictureCommonFragment.java:1254 after the system picker result. Reproduce the reported flow on Android 11 with the listed device details, then trace which value reaches java.io.File and identify the conditions for the NullPointerException. Done means the flow no longer crashes and the affected behavior is covered by an appropriate regression check.
