Segmentation fault on every project since this morning (windows 10)

monegator

Hi,
since this morning i'm having segmentation faults whenever i launch a debug session.
Earlier today two possibly related events happened: I had the graphics driver fail, right after it restarted the windows update icon appeared and proposed an update to the intel graphics driver (Intel Corporation - Display - 31.0.101.4953)

After this crash, when i launch a debug session i get a segmentation fault showing a bunch of assembly lines. hitting continue gives another segmentation fault, this time upon calling Release in this function in qwindowsopengltester.cpp

QDirect3D9Handle::~QDirect3D9Handle()
{
    if (m_direct3D9)
       m_direct3D9->Release();
}

if i hit continue, the application starts.

This happens also if i create a new Qt Widgets application.
This doesn't happen outside of a debug session.

Launching a debug session i see the usual stuff i've been seing since i started developing with Qt5

I'm running Qt 5.15.2
MinGW 8.1 32bit
Windows 10 22H2

i updated the driver, restarted my PC, but this annoying problem is still there. I wonder if someone else has it/has an explanation/has a fix?

Edit: I made some tests and it seems the segmentation fault only happens if i start a debug session with a 32bit kit.
Qt 5.15.2 64bit does not result in segmentation fault. Qt 6.6.1 64bit does not result in segmentation fault.
Unfortunately i must support 32bit executables

31.0.101.4953 is old, try updating to a newer version

Have you tried cleaning your project and recompiling completely fresh? Maybe some old things are still linked in.

Will try a newer version and report back

You should be able to install Intel drivers from Intel site on Dell machines (was working for me just fine in the past).
