Steps to reproduce:

1. Install or build Qt 6.9.2
2. Build either qtquickview_java or qtquickview_kotlin example
3. Run the example

Expected:

    Example runs without issues

Actual:

    Qt Quick components fails to start and shows only white

Based on my study this only happens in 6.9.2 (or the 6.9 branch) at the moment - 6.10 beta 3, the 6.8 branch, the 6.10 branch and the dev branch look to be fine. Further investigation revealed than reverting https://codereview.qt-project.org/c/qt/qtdeclarative/+/655056 fixes the issue. The weird thing is that 6.10 and dev also have the same commit but still work fine. :shrug:

Logs from a working (reverting the aforementioned commit) and non-working app startup are included as attachments. I was unable to find any meaningful differences from them.
