Qt creator editor crash while opening very wide files

Step to reproduce:

1.  open a Qt project;
2. add a width file like some min.js library (all in one line). for example : https://cdnjs.cloudflare.com/ajax/libs/vue/2.6.11/vue.min.js
3.  opening Editor see GUI blocked or have no response and then crashed.

such VScode other editor will crash while open same file. this can be reproduce both on Windows10/11 and Linux OS.

EDIT: sorry I cannot access the problem PC and can you try a more width file like this:https://raw.githubusercontent.com/shun2wang/jasp-desktop/JsCleaning/Desktop/html/js/mathjax-tex-svg-full.js

if still not I'd like to add debug info from Qt creator later. with thanks.
