Comment 1 TraceyC 2025-03-10 18:44:04 UTC 
Thank you for the bug report. I'm not able to reproduce this on git-master. Unfortunately the backtrace is incomplete and missing debug symbols for the following line that we need to figure out exactly what's going wrong:

#16 0x00007327f5773551 in ?? () from /lib/x86_64-linux-gnu/libKF6KIOGui.so.6

Could you please install debug symbols and attach a new symbolicated backtrace generated by using coredumpctl gdb in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!

I reinstalled that device since, but looks like I can't reproduce it anymore on 6.3.2 :)
