As the message at the top of the summary says, if something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ?

Thanks.

So i followed the Instructions, not sure if this backtrace will be any useful but:

this is the result i got:

Thanks. Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

Could you please install debug packages 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!

Created attachment 185433 [details]
KDE crash report + debugging symbols

Heya! sorry for the delay, its been quite busy recently.
i've yet to do a coredump gdb with the debugging packages, I'm planning to do that soon
for now I've saved the crash details through the KDE crash reporter with debugging symbols and attached the .kcrash file
let me know if the attachment is enough or if you still need the backtrace from gdb through the terminal.

Thanks! The new backtrace is more useful.
