Thanks for the bug report. I'm sorry we weren't able to get to this yet. There have been many fixes and improvements since this was reported, and this issue may have been fixed.

Can you please re-test on your system with Plasma 6.4.3 or later and let us know if you can still reproduce the crash?  If this is still crashing, 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.

I can confirm this bug doesn't exist since plasma 6 but unfortunately I am not familiar with bug reporting so I don't know how to close this one
