[Interest] codesign issue with Qt6.9.1

Hello all,

I just upgraded from Qt6.5.3 to Qt 6.9.1 – it's all fine except that now the codesigning fails. I typically do:

macdeployqt My.app 

codesign --options=runtime --entitlements ./deployment/entitlements.xml --deep ./My.app -s "My dev account"

but when I check it via:

codesign --verify --deep --strict --verbose=2 ./My.app

I get this:

./My.app: invalid signature (code or signature have been modified)
In subcomponent: /Users/soulalex/my-app/mycode/my.app/Contents/PlugIns/iconengines/libqsvgicon.dylib
In architecture: arm64


Can anyone advise what to do in this case ?

Thanks beforehand and best

Alex
