@uauauaua said in QtCreator 19.0.1 Total crash when copying source code:

For some time now, I've been experiencing sporadic problems with Qt Creator. When a source code line or block is selected, the PC enters an infinite loop if I try to copy the source code to another location. This then requires aborting and restarting. With Qt Creator 19.0.1, the error occurs immediately.

Working with version 19.0.1 is absolutely impossible.

This is all running on Windows 11 Pro Edition, version 25H2, installed on July 29, 2025, OS build 26200.8246, Windows Feature Experience Pack 1000.26100.297.0

I have similar experiences with code folding. Try to expand all code before pasting. Maybe this can give a hint to the problem.

@uauauaua Can this be reproduced always? Do you have a specific file or minimal project that you can share?

QTCREATORBUG-34366 sounds related and currently needs a reproducer.
