It crashes in QByteArray. The maximum size for a QByteArray is 2GB. I have created a test image with 1.5GB and could not reproduce the problem. How much memory do you have in your computer? Please try with the digiKam-5.9.0 pre-release AppImage: https://files.kde.org/digikam/ Maik
I do not know about what happens under the hood. 750 mbyte is on disk. and it is a compressed TIFF. no idea how big it is in real memory.
