Comment 2 TraceyC 2025-09-16 18:57:51 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 lines that we need to figure out exactly what's going wrong:

#0  0x00007efccb1393f8 n/a (libQt6QuickTemplates2.so.6 + 0x1393f8)
#5  0x00007efcd35542c3 n/a (libQt6Qml.so.6 + 0x3542c3)
#12 0x00007efcd21d466f n/a (libQt6Core.so.6 + 0x1d466f)
#28 0x0000556bb49ad3f1 n/a (/usr/bin/plasmashell + 0x283f1)

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!
