Hello,
I tried to reproduce this inside a minimal stable/bookworm VM
and received a qmlcachegen crash.
See attached file for details.
The resulting backtrace is quite similar to that found in:
https://bugreports.qt.io/browse/QTBUG-117361
Might avoid the crash, but cannot say if this would make the build succeed.
Kind regards,
Bernhard
