Comment 1 Nate Graham 2022-10-24 20:24:02 UTC 
Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

#4  0x00007f49e5923b98 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/plugins/discover/flatpak-backend.so
#5  0x00007f4a05ce89af in ?? () from /lib/x86_64-linux-gnu/libQt5Core.so.5
#6  0x00007f4a07ec629e in Transaction::statusChanged(Transaction::Status) () from /usr/lib/x86_64-linux-gnu/plasma-discover/libDiscoverCommon.so
#7  0x00007f4a07ec66ec in Transaction::setStatus(Transaction::Status) () from /usr/lib/x86_64-linux-gnu/plasma-discover/libDiscoverCommon.so

Could you please install debug symbols for Discover and its flatpak backend package, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
