I was able to reproduce this bug on two Arch desktops, I have attached the logs for reference. Can anyone confirm if its the same bug?
Comment 3 Nate Graham 2021-02-25 21:26:08 UTC 
Unfortunately the backtrace looks totally useless. :( Any chance you can re-compile with debug symbols, reproduce the crash, and attach a new backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Arch

Thanks!
