SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Use discover until a fresh installed application crashes (for me it occured with openshot video then kdenlive) 2. Force reboot computer as nothing respond 3. Get stuck at launching messages SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: 5.27.5 ADDITIONAL INFORMATION It could be interesting than sometimes discover crashed with a notification on the bottom right of the desktop. I also noticed before the crash I see the app icon appeared in the task menu and dispappeared strait away. Then I still can move my mouse and select things but nothing respond anymore.
I'm afraid there isn't enough information to debug this. I would recommend asking for help at https://discuss.kde.org/c/help/6. The folks there can help you determine what the problem is and whether it's caused by a bug in any KDE software. If that's determined to be the cause, please don't hesitate to come back here, re-open this bug report, and describe what the problem was determined to be. Thanks a lot!
