Yes, you are correct, TestComplete version 15.72, released on February 5, 2025, added as an improvement Qt 6.7 support https://support.smartbear.com/testcomplete/docs/general-info/version-history/features-added-to-ver-15-72.html
However, it's important to note that TestComplete's official documentation specifies support for Qt applications built with Qt versions 5.15 and 6.2, which are considered Long-Term Support (LTS) versions.
Desktop is not my expertise and as no one else in the community responded you will need to further engage with support.
To debug and isolate, as I requested in my earlier post, it would help if you download the sample and try it out. If it does not work for you, it means we are looking in the wrong place.
QT 6.2 is no longer in LTS it ended last year.
I do not know why Smartbear has not updated their documentation that is on them, but the current release of TC does not support QT 6.2 at all. That support was removed with the 15.72 update, and per support that was on purpose(doesn't make sense to me, but that is what we have been told).
I have already reported the issue to support, just looking to see if others are experiencing the same issue or have tried it because I am hoping for a quicker solution than waiting the support team.
Thanks

Their documentation is not always up-to-date! However, if you have confirmed with Support, then it should support it!
My guess is, is that TC is broken.
