The crash is in some bits of the application framework binder. Is there a way you could add some of the code you're using? Also, adding the entire journal might also reveal something, and presumably adding all of that in a JIRA ticket. /cc Jose, Stephane, maybe they have some clues for it. > #4 0x0000aaaaaaab3f70 in Shell::fullscreen_view (this=0xaaaaaac264e0, fullview_flag=<optimized out>) > at /opt/agl-sdk/11.91.0+snapshot-aarch64/sysroots/aarch64-agl-linux/usr/include/c++/9.3.0/bits/basic_string.h:2300 > #5 0x0000aaaaaaab0a54 in Shell::qt_static_metacall (_o=_o@entry=0xaaaaaac264e0, _c=_c@entry=QMetaObject::InvokeMetaMethod, > _id=_id@entry=1, _a=_a@entry=0xffffffffa748) > at /home/manikandan/QT_apps_workspace/radar_popup/build_popup/app/parking-assist_autogen/EWIEGA46WW/moc_shell-desktop.cpp:106 > #6 0x0000aaaaaaab1078 in Shell::qt_metacall (this=0xaaaaaac264e0, _c=QMetaObject::InvokeMetaMethod, _id=1, _a=0xffffffffa748) > at /home/manikandan/QT_apps_workspace/radar_popup/build_popup/app/parking-assist_autogen/EWIEGA46WW/moc_shell-desktop.cpp:172 > #7 0x0000fffff7aad928 in ??
