@uweseimet The issue persists in issue_247 fa63022 – and I didn’t need a 4GB file, it happens also with a 2048 MB file created with develop web ui. It seems that’s the size that triggers it too. If you have a 2047 MB file, there’s no crash (didn’t test down to the byte.)

This is with a Pi 3b with a fresh Pi OS created by the official Pi imager tool, and all packages at the latest version (apt upgrade)
