Crash when packaging

Describe the issue

Python Stack Trace Windows fatal exception: access violation

Current thread 0x00002eac (most recent call first): File "C:\Users/Ronan/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\qfieldsync\gui\package_dialog.py", line 177 in package_project offline_convertor.convert()

Reproduction steps

I managed to get it to only throw an error by adding each layer i want to export one by one to a new project, and packaging them one by one until something didn't work. By doing this it threw an error (but didn't crash) in the python log only after i added a particular geopackage with some polylines.

2024-06-27T12:41:55 WARNING Traceback (most recent call last): File "C:\Users\Ronan\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\qfieldsync\libqfieldsync.whl\libqfieldsync\offline_converter.py", line 568, in _on_offline_editing_next_layer layer_name=self.__offline_layer_names[layer_index - 1]

             IndexError: list index out of range

That geodatabase had three lines within it, however i did not have them in a folder in the layer panel. When i put them into a folder in the layer panel and tried to package again, the error went away and everything packaged fine. (the geotiffs to be packaged were already copied into the qfield export with their Action set to Keep existent(copy if missing) set.

This fix didn't help with the original qgis project, it would still crash no matter if the polylines in question were in a folder, and even when they were the only layers set to Keep existent(copy if missing).

Cheers
