hi,

Formatting tip
When posting terminal output - quote may look nice - but code looks better

Example: select the text and presse the </> button in the toolbar or press Ctrl+E

All I can say is: Make sure your system is up-to-date.

If it is up-to-date I would be suspicious of text

EDIT:
I have verified on my main workstation

Operating System: Manjaro Linux 
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1
Kernel Version: 6.18.2-1-MANJARO (64-bit)

qtcreator does not segfault on my system - that does not imply anything but the fact that I cannot reproduce it.

Qt creator works fine for me.

This would be the first thing. Please check the version numbers of Qt creator and the qt6-... packages. If this is ok, test with another user just to be sure. If it runs into the same segfault you need a stack trace that is helpful. You find these with coredumpctl list and you symbolise a specific entry (if the corefile is still present) with coredumpctl debug [PID].
