Description
In looks like something has changed in the deployment process of Qt Applications from version 5.12.5 / 5.13.0 to 5.14.0beta1. I'm using 5.14.0beta1 because of the new HiDPI features.
QtWebEngine cannot find its resources anymore, because the library paths seem to have changed to the parent directory of the running application. Due to that fact, my application crashes, because QtWebEngine aborts the application.
I didn't change anything to my deployment process and installer creation process. Also the application works well with Qt 5.12.5.
A workaround is to move the QtWebEngine resources and the translations directory to the application directory. Also adding a qt.conf with
'Prefix = c:/Program Files/zc4'
helps.
