A Qt 6.6.2 application crashes inside the Intel driver if the executable name contains non ASCII characters. The attached example causes a crash if the executable is named "tést". If the name is changed to "test" no crash occurs. Here is a stack trace:

The crash is probably caused by an Intel driver update. We observed that the application does not crash by using Intel driver version 31.0.101.4575 but crashes by using version 31.0.101.5333. So far we were not able to reproduce this issue on Windows 10.
