QT/VisualStudio Assertion failed only when debug

elicat

Hello in my project into Visual Studio 2019 I setting
alt text

And although apparently i have not done anything new but just recompiled the project, when i debug i get this error
I specify that I have not used any assertions in the code created

alt text

For now, I'd be content to disable it to proceed with the work in debug mode but everything I've tried doesn't seem to work.
I have put into file.PRO NDEBUG

DEFINES += QT_DEPRECATED_WARNINGS NDEBUG  QT_DISABLE_DEPRECATED_BEFORE=0x051200

And i Have try when compiled

Any ideas to solve the problem?
Why does this happen?

Thanks

@elicat
This is a runtime error, nothing compile-time. The assert() is in the mentioned mathutil.h file.

Rebuild from clean/scratch/delete everything generated. Run from VS. Press the first button on that message box. Find the stack trace window in VS. Look at the call stack. See where the faulting code has been called from, diagnose the problem.

I followed your advice but found nothing useful

When I build program into debug i have this error in windows output

Debug Error!
Program: ...\OneDrive - ELICAT SRL - 03978700288\GrareGUI\GrareGUI_dc.exe
abort() has been called

And this in QT console

. . .
Assertion failed: bits != 0u, file C:\Users\qt\work\qt\qtbase\src\3rdparty\angle\src\common/mathutil.h, line 927

And into call stack this

Under these conditions I have no reference to understand the problem to be solved

The other strange thing is that there is no path

C:\Users\qt\

Can anyone help me?

Hi,

Try forcing the backend to something else than angle.

Hello, I'm sorry but I didn't understand what it means

Check the Graphics Drivers part in the Windows platform documentation. It explains the various possible backends as well as how to force the selection in your application.

Good morning
My project uses QtWebEngine.
I don't think it's a windows graphics setting.
Many forms are opened without errors even in debug but to some forms at the end of their loading the Assertion problem is issued.

A specific form, opens without problems and then clicking on a tabs that opens a section of the form (therefore a jquery / boostrap action) produces the assertiveness error.

The error reports the following library:
libGLESv2.dll Assertion Failed

I also tried to install a new version of Qt but I had other problems that led me to open another ticket
