    Hello,

    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? I am unable to find any information on it.
    Thanks.

    Edit: I am running it on Windows 11

      Just so you know, I believe this error message comes from you using MSVC (right?). It's to do with delay-loading of DLLs at runtime. Something to do with https://learn.microsoft.com/en-us/cpp/build/reference/understanding-the-helper-function and https://devblogs.microsoft.com/oldnewthing/20170126-00/?p=95265. That's just FYI, I don't know what its trying to load or what you can do about it.....

      I have narrowed it down a bit. I ran a Windows update (KB5023774) for the PC and I did not consider that this error could have started after this update.
      TMUMH might be connected to "Trend Micro Security" Antivirus dll hooks (probably tmumh.sys - I am not sure). It is installed on the system and maybe the Windows Update might have disturbed something related to the Trend Micro - Windows cooperation.

      Thank you so much for responding and directing me to the right way. I guess I will have to wait till Trend Micro Security releases an update and maybe that might solve the issue.

            @Kevin470 I'm seeing the same issue after Windows 10 update KB5023773 and am running Trend Micro Security Agent 14.0.12032.

              We have the same problems in our company with Qt 4.7, 4.8, 4.9, 5.12.
              I have uninstalled the cumulative update KB5025221 for Windows 10 22H2 from April.

              Now the problem with trend micro, windows and Qt is solved.

              Best regards Ralf

                @Kevin470 Hi, I have exactly the same problem with you and i also have Trend Micro Security on my laptop. I have been searching this issue for a few days. Have you tried to close the antivirus software? Could this solve the issue?
