I have an error that pops up on the application output when I run a project which says:

[Error] DelayHook can't open TMUMH_DELAY_HOOKING_MUTEX, error code: 2

It keeps being printed on the application output every second or two.

As far as I can see, it does not affect the program anyway.

I tried creating two new projects, a fresh console project and a fresh Widgets project and run them without editing anything. They had the same error message printed on the output.

What could be the reason behind this Error Message?

Did you try [this](https://forum.qt.io/topic/144001/delayhook-error-qt-6-4-3)? – Abderrahmene Rayene Mihoub Apr 24 '23 at 07:42
I try that. I don't use Trend Micro Security. My mistake was caused after installing OpenCV. I suspect that it may be due to adjusting related environment variables, which resulted in constant errors. – Edward Apr 25 '23 at 00:17
After a minor Windows 10 update, QT started working normally again. – Edward Aug 24 '23 at 07:50
